Eunhwa: Tactical UpgradeInformation and Guide

Summary

Can you give a brief summary about this unit?

For the full context, we recommend skimming through TEmma's guide first because some info that has been presented there may not be presented here again.

Eunhwa: Tactical Upgrade (referred to as TEunhwa for the remainder of this guide) is a generalist B2 and an enabler. Alone, she acts like a SRosanna lite, debuffing enemies with Damage Taken▲ for 10s on Burst and increasing the team's Charge DMG. Even so, her buff values are relatively smaller, so she is far from optimal as a solo B2. As an enabler, she empowers TEmma, unlocking numerous abilities for her and also herself. An enabled TEmma provides extended S1 uptime & bonus True DMG for the team, whereas an enabled TEunhwa provides True DMG for the team and a strong ATK▲ for self. A total of ~62% True DMG▲ is given to the whole team.

While TEunhwa can operate alone, she has a lot of weaknesses (compared to other meta B2 choices). Firstly, there is no ATK buff to self, so her damage will be mediocre at best unless buffed. Her Damage Taken▲ is also a targeted debuff that doesn’t affect the whole screen despite impacting a large area; it also doesn't debuff new enemies. Thirdly, she has nothing else to offer other than her own minimal personal DMG and Damage Taken (27.87%▲ is lower than SRosanna’s and Blanc’s Damage Taken and may not be better than ~40% ATK DMG buffs). Her 42.24% Charge Damage▲ is also barely even useful. Many modern units rely on skill damage and not Charge Damage, making it worse than SRosanna's ATK▲ or Sustained DMG▲.

Insight: Even without TEmma/TVesti, TEunhwa is still the second flexible Fire B2 worth using in Raid after Grave. Other Fire B2 do not provide extra firepower. If you need someone to break Fire QTE, she can help.

With TEmma, things change for the better. TEunhwa now offers something that SRosanna can't: personal damage and immense True DMG▲ for the team from herself & TEmma. This is their selling point—pair them with units that deal True DMG and you shall witness marvel. We spoke of this in TEmma's review, that TEmma + TEunhwa are an "acceptable" generalist duo, but their forte is buffing True DMG DPS, where their value suddenly rises dramatically. With TEunhwa dealing quite a bit of True DMG if played right (manual control may be required) and being affected by the team's True DMG▲ as well—she constitutes a considerable portion of the team's damage.

Where can I expect her to be used?

Like with TEmma, we believe she holds a role in Fire-Weak SR (incl. Museum, which has high DEF), UR, and potentially Campaign. She also has a high chance of being usable in Elysion Tower mobbing. In high-rank SR (Top 100+), TEmma + TEunhwa + TVesti will definitely be used in the next SR against Ziz, which has a lot of DEF and suits them well. They may also be used against normal Fire-Weak(s), probably replacing Cindy comps. Against other elements, their usability depends on whether there are other DPS that are worth pairing them with, either in the future or now. Ein is a notable Electric True DMG DPS and LaplaceTr is a "good" Iron True DMG DPS. In low-rank SR (~3%), you can split TEmma + TEunhwa from "True DMG DPS" and treat them as a regular duo if you don't have better B1 + B2 combinations or lack the other duo(s). You can also use solo TEunhwa as a lite SRosanna or B2 Fire QTE breaker, especially in Cindy comps, which in the past has been using Grave (or straight up nothing aka bruteforce).

The same logic also applies to UR, but in UR, they are probably less preferred because, in an ideal situation, you only hit each element once. The issue is that there is a better Fire Team than this trio. Rapi: Red Hood, Grave, Asuka, Alice, Rei, and Mihara can provide overall more impact with universal supports. However, if you are forced to hit one element multiple times or you lack a proper Fire Team, you can definitely use this trio as your primary or as your Team 2 or Team 3. You can also split TEmma + TEunhwa from TVesti and treat them as a regular duo. You can also use solo TEunhwa as a lite SRosanna or B2 Fire QTE breaker. For low-sync players, this duo (or maybe even trio) might help players do more damage in UR Hard Mode, since dealing true damage can help offset the DEF values of these bosses.

In Campaign, their usability depends on the element of the stage and the availability of a good True DMG DPS in that element. On Fire-weak, TEmma + TEunhwa + TVesti can be a strong contender, as well as in Electric-weak with Ein. We have not seen amazing results with LaplaceTr before, likely because there are better Iron DPS, but there are stages Laplace did shine in. This is not the case with Ein, who has two niche bosses and in general is a strong mob clearer. How about their performance without TVesti or other True DPS? They are worse, of course, but you can still use them like a regular duo. Just don’t expect them to overpower Crown or something. Even then, True DMG is still very good in High Deficit Campaign, so let’s not underplay that.

In Elysion Tower, many meta Campaign units don't co-exist, making Tacticals + TVesti trio more dominant. Their direct competition is Maids (Mast Maid + Anchor Maid), who have a weaker start but become stronger in longer fights. We believe, in mobbing, Tacticals will win due to their better start, and TVesti is undoubtedly the best Elysion mobber now (even better than Rapipi). In bossing, Rapipi is still a better bosser and there are good secondaries like XMaiden and HelmTr (who might be stronger in their elements), which raises the question: can Tacticals beat them? You cannot use Rapipi B1 with Tacticals, by the way.

In PvP, solo TEunhwa is likely not going to be used by top combatants because she serves nothing new. In fact, she is worse than most meta B2 PvP units we have right now because her buffs are weaker and Camouflage can jumble expected targeting. She also has inconsistencies with her Burst Skill applying before or after B3’s Burst Skill. Regardless, you can still use her as a teamwide Damage Taken applier who doesn't feed (SR) but inflicts AoE damage (similar to Mari). That said, if TEunhwa is paired with TEmma and is deployed with True DMG DPS like TVesti and Ein, they can buff them immensely even from the zeroth second. With TVesti, they can form an unexpected combo that annihilates Wind Nikkes in P1, P2, and P3 and potentially interrupts their Burst Chain. This is a niche team that might see use for countering certain comps.

Performance assumed with our current calculations for TVesti, but her mechanics may end up different than our predictions.

Should I pull for her?

We shall preface this with NO, just because we are anticipating a potential collab this year and getting a trio is quite expensive. You should also be saving your gems. We don’t know whether the next unit is broken—but, we know for sure that they have to release broken Pilgrims on Anniversary or people will be disappointed (flashback to Red Hood). If you pull TEunhwa, you will have to also pull TEmma & TVesti ideally, which is costly and may not be viable for F2Ps. It is not a problem if you are a Spender, though.

If you like experimenting with new teams (esp. in Campaign), want to compete in Fire-Weak SR (Top 100+), or want to be ready for when ShiftUp releases a hypercarry True DMG DPS, then feel free to get TEunhwa (as well as her partners). We are not going to stop you, but we also can’t guarantee that we will get a hypercarry True DMG DPS. It’s all hypothetical anyway, but you will still at least gain some value out of them in the next SR against Ziz (and maybe Campaign too). If it happens, the skippers will have to test their luck on Ordinary Banner (Wishlist) and random Advanced Banner drops.

Finally, should you mileage her? No. Mileaging three 2% units is a fast track to draining all your reserves. Should I get dupes for her? No. TEunhwa does have a self-ATK buff, but since she deals True DMG, the damage gain is slightly less. Also, if you get dupes for TEunhwa but not TEmma or TVesti, it will just create discrepancy and unhealthy dependence. And, if you get dupes for all of them, say goodbye to your wallet.

Kit Analysis

Skill 1 - Basic Attack = Source of Damage (Very True)

Upon using Burst Skill, and whenever she lands a Fully Charged Attack during Full Burst, TEunhwa gains Camouflage, preventing her from being targeted by single-target attacks for 5s or until she takes damage from AoE.

• Permanently active on Auto Aim, although you should manual her for Burst Gen if it is needed. On certain conditions, you can also quick-shot (spam-shot) her to min-max her damage between the 5s intervals (read Gameplay Optimization below).

• Extending the previous point, make sure to Full Charge before Camouflage drops.

• Useful in Campaign if you want to Burst Gen with her while your whole team is in cover. Since TEunhwa is the only one exposed yet untargettable, she can’t randomly get one-shot. Attacks will still go to her allies.

• Handy when manual-controlling her because you can completely focus on maximizing your damage rather than worrying about attacks hitting you (a problem with Alice/Red Hood).

• Activates the second part of this skill.

Whenever TEunhwa attacks during Camouflage status, all her normal attacks deal True DMG instead. She also gains 42.24% True DMG▲ continuously.

• Activated by the first part of this skill.

• Since Camouflage status is effectively permanent, that means all her attacks are True DMG. This makes her synergize well with True DMG▲, even better than TVesti does. The True DMG▲ for self here is also permanent.

• The damage is from her normal attack ratio, which means all buffs that increase her Basic Attack DMG, including but not limited to Charge Damage, Charge Speed (shortens interval), Sniper Rifle Doll Skill, Core DMG▲, Normal Attack Damage▲, CRT Rate▲ for Normal Attacks, and so on, increase this skill’s value.

• Very good against Bosses with high DEF and for High Deficit Campaign. You can break boss’s parts that have high DEF easily (note that most skill damage doesn’t damage parts, but TEunhwa’s damage is not skill damage; it’s basic attack). This makes her advantageous against Ziz, who spawns high DEF parts that deal AoE damage if not destroyed.

Skill 2 - Pair With TEmma = Team Buffs

TEunhwa grants herself and her team a variety of miscellaneous buffs that can potentially increase personal and team damage significantly:

• Whether TEmma is in the team, she grants AS Formation, which enables TEmma’s, and also:

  • To Absolute squad members: Critical Rate ▲8.16%.

    • Synergizes with TEmma’s Critical Damage. Otherwise, value is negligible.

  • To all allies: Charge Damage ▲41.81%.

    • Only good for units who are reliant on Charged Basic Attacks (TEunhwa herself, Alice, RH, SBS, Maxwell, and SR/RL units that don't depend too much on skill damage).

    • TVesti is ironically not one who benefits from this the most because her damage is mostly skill damage, but damage boost = damage boost.

  • To self: ATK ▲42.24%.

    • Improves personal damage. Impact is more noticeable when the enemy has less DEF because True Damage will not dilute it (as it can be said that True Damage grants ATK equal to enemy DEF).

• If TEmma is also in the team and is alive, she further grants:

  • To all allies: Explosion DMG ▲5.11% and True DMG ▲30.97%.

    • Explosion DMG only affects Explosive ATKs (RLs/certain skills like TEunhwa’s own Burst), functioning as ATK DMG. Value is low, however, but it can stack up with TEmma’s and grant a nice boost. Does not affect Skill DMG.

    • True DMG is insanely good, but it only affects True DMG (functions as ATK DMG).

Burst Skill - Damage Taken For Bossing Only(?)

TEunhwa equips a special weapon that only has 1 Ammo. After charging for up to 0.3 sec, TEunhwa launches an explosive round that deals up to 105.6% × 300% = 316.8% True DMG (buffs not factored in). Target(s) hit are affected with 27.87% Damage Taken▲ for 10s. TVesti via Skill 2 deals additional Explosion DMG to enemies affected (although TVesti doesn't really need it).

• If you are not careful, your B3’s Burst Skill might land before TEunhwa’s Damage Taken is triggered, causing substantial damage loss. Some B3 skills only take effect after Full Burst, but some take effect exactly before.

  • It may even be late even on AUTO BURST SKILL. This can happen if TEunhwa triggers Burst Skill immediately after finishing an automatic shot, forcing her to spend an extra 0.2s in cover animation before charging again. The fix is to manual her and cancel the animation.

• That said, delaying TEunhwa’s Burst Skill’s Charged Attack until Full Burst begins makes it deal more damage. Use it if her damage is more important than the B3’s skill initial damage (if it’s the exactly before type)—usually the case for Campaign mobbing.

• This damage is Explosive and True, which means it benefits from Explosion DMG▲ and True DMG▲. It is also buffed by Charge DMG▲. However, the damage ratio is small, so don't expect too much from it.

• Damage Taken is not full-screen but impacts a large area (1500 = equal to A2/Emilia on Burst).

• Damage Taken does not apply to new targets that enter that area.

• This makes it slightly worse for mobbing but still very effective for Bossing, because it’s rare for bosses to feature mobs (and even then, the mobs are minor and can easily be killed).

• In Mobbing stages, land the Exploding Bullet somewhere that hits as many targets as possible, especially the stage target because it takes the longest to kill, so you gain more value out of it.

• In Mobbing, the Exploding Bullet may deal enough damage to kill small enemies, helping you take care of squishy but high-damaging mobs like Bullwhips.

• Activates TVesti’s S2—when attacking targets affected by Exploding Bullet, increase self’s Projectile Explosion DMG by 20% for 3 sec. Since Skill DMG ≠ Explosion DMG, and TVesti’s damage is mostly Skill DMG, the value of this skill decreases, but it still increases her normal attack damage (which is a tiny part of her damage).

• Damage Taken▲ belongs to a different category from ATK DMG▲ and is usually less diluted. Due to its multiplicative relationship with other buff categories, Damage Taken▲ is valuable. Whether TEunhwa’s Burst Skill is better than other B2’s, however, depends on team comp. Units with high ATK DMG▲ should benefit more from Damage Taken▲, but usually supports have other skills accompanying (like Mari giving ATK▲ and possibly Pierce DMG▲).

Gameplay Optimization

An ideal TEunhwa’s gameplay is similar to Trony’s. You Full Charge or use Burst Skill to get Camouflage, then spam shots till the next Full Charge requirement.

If TEunhwa is the only Sniper Rifle in team that can generate burst gen quickly through quick shots, practice 5 optimization techniques:

• Pre-reloading ≤2.8s before Full Burst ends (1s + 1.767s reload time with Resilience).

• Holding Full Charge ≤1s before Full Burst ends (1s Charge Time).

• Releasing Full Charge right after Full Burst ends to get a burst of energy.

• Then, quick shot till the next Burst Chain.

  • If TEunhwa reloads before Bar is filled, then quick-shot slower (hold/charge slightly longer, so each shot accrues more energy).

  • Do not slow down if you have enough ammo to get to the next rotation.

• Repeat until the battle is over.

With 14+ Ammo and no external Reload Speed other than Resilience, TEunhwa should also see increased personal damage from quick-shotting if Camouflage is up (note that Camouflage is refreshed via Full Charge on Full Burst/Burst Skill use). If no Max Ammo, avoid doing this because her long Reload Time (2.0s) will ruin her damage more.

With 6–13 Ammo, you can charge your quick shots slightly longer to balance between ammo consumption and damage per shot.

Note that these tips also apply to all SRs and some RLs. Some may only want to Full Charge if possible.

Tier List & Performance Analysis

To avoid redundancy, we have moved some information to Summary (because we want it to be more accessible for people who don't want to read). This section is an extension that discusses from the perspective of performance, whereas Summary is from the usage perspective. Both are used when deciding ratings.

Campaign (LD): S | Campaign (HD): S

Like we described in TEmma’s review, TEmma + TEunhwa together are high performers in both Low and High Deficit. This is because they have teamwide ATK buffs; Damage Taken; continuous Healing, which may come handy; and a bunch of other buffs. TEunhwa also deals notable damage herself because she deals purely True DMG + Burst Skill helps with mobbing. They are also Fire and deal more damage against Wind. However, they are not necessarily better than other duos for four main reasons.

Firstly, they require a CDR whose Burst Skill likely won’t be used (unlike with Tia because of re-enter). Since TEmma + TEunhwa are B1 + B2 respectively, that means you can only bring 2 B3. There is no HelmTr, MastM, RH-B1, or Crown flex unless you want to sacrifice CDR. If you can live with no CDR, then this is not a problem, but nowadays Campaign is mostly CDR + B2 + B3 + B3 + FLEX.

Secondly, TEmma + TEunhwa are only potent with True DMG DPS. While they have a slew of generic buffs, those buffs in aggregate are not more than certain other duos’ or B1 + B2 + FLEX combos’. They only become stronger than them when True DMG is factored in. This is because, even if their numbers are higher on paper, they need to compensate for the restricted CDR last slot with more firepower.

Thirdly, if either TEmma or TEunhwa dies, their link breaks because they must stay alive to grant AS/LT Formation. This disables most of their buffs and forces you to retry unless the enemy is close to death. Sometimes, you cannot control who dies, and some stages may require deaths/sacrifices of one or two “random” units. That said, TEunhwa has Camouflage, so she is the least likely to die.

Fourth, TEunhwa’s Explosive Bullet, while able to kill enemies at High Deficit due to its notable True damage, does not apply to new enemies that spawn. This makes it good for quick crowd control but less for continuous wave clearing. Some stages, especially Defense Stages, feature continuous mobs spawn instead of grouped waves. While you can stagger your Burst Skills and wait before the next Wave sometimes, you can't abuse all your buffs at the same time.

Solo TEunhwa, on the other hand, is probably a better SRosanna in Campaign, whose S1 likely won't activate because she needs parts. TEunhwa has a slightly less Damage Taken value, but she has personal damage, burst gen, and is capable of “crowd controlling through damage” with Burst Skill. She also gives Charge Damage▲, which albeit not versatile, is handy for meta Campaigners like SBS, Alice, and RH. Yes, she can function without TEmma and still retains her S tier (in Low Deficit, at least).

Bossing: S

With TEmma, TEunhwa + TEmma is basically a duo that is slightly better than Blanc for all units (except when team-building limitations exist) and significantly better than most duos (incl. Maids) for True DMG attacks. Hence, whether they are better than other duos is dependent on how much True DMG is dealt by the team (not the number of True DMG dealers). Note that, with the current roster, they will almost always require an off-burst CDR (in-burst is fine, but likely wasted), which adds a layer of restriction.

TEmma + TEunhwa have advantages that other teams don't. They are Fire, so they deal more damage to Wind bosses and can break Fire QTE. TEmma also heals a lot, though not as much as Blanc. TEunhwa can also deal great damage to parts. TEunhwa being SR makes burst-genning with this team slightly easier than with, let’s say, Liter + SRosanna, Maids, and Blanc + Noir. However, all of these are overshadowed by the fact that off-burst CDR must be used, and you are forced to choose between that CDR’s Burst Skill or TEmma’s/TEunhwa’s (no re-enter).

Without TEmma, TEunhwa remains a usable B2 (whereas solo TEmma = bad). She becomes a “lite Grave”, possessing a similar playstyle albeit having a kit more akin to SRosanna’s. TEunhwa is capable of inflicting Damage Taken for 10s and boosting the team’s Charge Damage while also delivering a bit of damage herself (increases relative to the team with higher enemy DEF). Her Burst Skill can also help clear adds if they are within range. While these sound acceptable, her values are lower than competitors, and the effectiveness and applicability of CHG DMG is very minimal (most units rely on Skill DMG). She is therefore usable but not better than most meta B2.

So, where does this “lite Grave” moniker come from? Well, you see, if you scan the B2 we have before now filtered by the element Fire, you will realize that there is only one worth using for offense—Grave. In Solo Raid, Grave has been used as a filler B2 for certain teams like Cindy Funnel (used to be common but less common nowadays). This allows Cindy teams to destroy Fire QTE and easily survive, although some choose to bruteforce and save Grave for somewhere else. TEunhwa now joins this pool of Fire B2, but since solo TEunhwa is worse than solo Grave, we call her “lite Grave”.

PvP: B

This rating assumes mostly TEunhwa’s solo rating in PvP, although combos (duos/trios) are also taken into account.

Solo TEunhwa is nothing more than a teamwide Damage Taken applier (+ a little bit of AoE). She is an SR, so she can generate burst gen without feeding, but those two are pretty much all her moves. Her Camouflage is not something that’s useful in PvP too; it prevents her from being used as a decoy for “targets the highest ATK” skills. That said, if TEunhwa is paired with TEmma and is deployed with True DMG DPS like TVesti and Ein, they can buff them immensely even from the zeroth second. Like we previously said in TEmma’s review, TVesti with TEmma + TEunhwa can form an unexpected combo that annihilates Wind Nikkes in P1, P2, and P3 and potentially interrupts their Burst Chain.

Since she is similar to Mari, she should have been A, but there is one hidden weakness we also mentioned in her Burst Skill analysis. Her Burst Skill is sometimes delayed and may land before or after B3’s Skill. That means it may or may not buff your AoE Wipe that triggers instantly. This RNG is what drops her to B. Someone like Emilia, though, doesn't care because her Burst isn't on impact; it’s delayed.

Investments

Gear Investments

Eunhwa is an Attacker by role but supporter by heart. Hence, she does not really need OL, but OLing her will directly influence her damage dealt, which is what Attackers do. She can be expected to deal pretty good damage for a B2, especially if paired with TEmma. 1-2 Ammo will help for burst generation, but otherwise Eunhwa wants 4× ELE and 4× ATK. 

• Essential: -

• Ideal: 4x ELE, 4x ATK, 2x Max Ammo

• Passable: Crit DMG, Max Ammo, Crit Rate

• Priority: Medium

Skill Investments

TEunhwa’s S2 and Burst are team-focused skills, while her S1 is selfish. Thus, you may keep S1 low until or unless you decide to optimize Eunhwa’s OL gear. That said, the impact of S2 reduces if she’s not paired with TEmma or True DMG DPS. Without them, the significance changes from Burst Skill >= S2 > S1 to Burst Skill > S2 >= S1. There are no specific breakpoints.

• Skill 1: 4/7/10

  • Only self True DMG buff.

  • Can be left low until OL gear is optimized.

• Skill 2: 7~10

  • This skill alone provides a multitude of squad buffs, team buffs, and self buffs.

  • This skill is of high importance when using TEunhwa (with TEmma) with a True Damage DPS, since this skill has a high value teamwide True Damage▲.

  • Becomes pseudo self-buff if not paired with any True DMG or Charged Attack DPS.

  • Higher priority to upgrade compared to Skill 1 but lower priority than Burst Skill.

• Burst Skill: 7~10

  • Small AoE nuke.

  • The enemies the nuke hits are inflicted with Damage Taken Debuff, which is meta and of good value.

  • Hence, invest in this skill to increase the team's damage the most regardless of the type of damage they deal.

  • The only versatile offensive (de)buff for the team.

Cube Investments

The usual Resilience is the best for her damage and most convenient for burst gen, regardless of whether you auto or manual her. Bastion may be better for compressing as many shots within x seconds for burst gen, but Resilience is fine. Choose whichever one has the highest level for Elemental DMG buff.

When she is up against Bosses with regenerating parts, using Destruction Cube is also a viable strategy since TEunhwa can deal a lot of damage to Parts (diluted by other ATK DMG/True DMG▲, however; with TEmma, she already has ≥100% True DMG).

Doll Investments

TEunhwa does not have a caster's ATK buff as a support, so Doll is not important. However, if you have her built for damage and want to minmax it, Sniper Rifle Doll’s skill (increase Base Charge Damage by x%) is pretty good and synergizes well with TEunhwa who relies fully on Basic Attack Damage. We recommend at least R0 → R15 → SR5 at least if you are serious about using her; this is enough for most players (even those who chase Top 100). Very competitive players can choose to go SR15.
