Review

Mr. Duncan, for better or worse, is probably one of the simplest character gameplay designs we’ve seen in a while, reminiscent of the OG characters who have been in the roster the longest. His gameplay essentially revolves around the mechanic of [Bullets]. He gains them either from his counter skill, which lets him acquire 2 bullets from the [Veteran’s Cartridge], or through his Insight III passive. With Insight III, he generates bullets for the entire team whenever he lands a critical hit or defeats an enemy, granting all allies one type of bullet. Additionally, every 3 critical hits he lands, he gains Moxie.

Now, you’re probably wondering: what do the bullets even do? Looking at the [Veteran’s Cartridge], it contains 2 types of bullets: [Acid Bullets] and [Shrapnel Bullets]. The effects are pretty simple: the Acid Bullet lowers the target’s defense by 5% (lasting 2 rounds) and can be stacked up to 5 times, while the Shrapnel Bullet lets you deal 50% additional damage. And that’s kind of the bulk of his kit.

He provides bullets for himself and others, gains Moxie quickly, and can use his Ultimate, which also increases Crit Rate by 10% for each type of bullet you have. This is further buffed by his Insight I, which provides [Ceremonious] (you gain a stack every 2 times an ally triggers [Bullets]), increasing his Ultimate Might by 3%. This can stack up to 100 times, making his potential Ultimate damage quite good. Though realistically the buff is only 3%, I can’t think of many ways to spam [Bullets] to the point where you can get his damage that high, at least not right now.

Additionally, things I didn’t mention: he has a Mass Attack, with a bit of random additional Genesis DMG included. He has counters with [Quick Draw] which when you have bullets, will launch Rapid Counter-Fire, which does single target damage and the unique part about it is, he can land the counter before they even hit him.

Pros & Cons
Pros

  • He gains Moxie pretty quickly through his own skillset, even faster in a Crit team, allowing him to use Ultimate fairly consistently which is a good source of damage. 

  • [Veteran's Cartridge] allows for good debuffs/buffs, with Acid Bullets reducing target defense and Shrapnel Bullets adding a significant damage boost.

  • Solid Crit synergy, thanks to his passive [Insight III], providing bullets for the entire team whenever he lands critical hits or defeats enemies.

  • He provides a unique Counter, where he can hit the opponent before they get to attack him. He also provides Genesis DMG. 

Cons

  • Damage Dealers have an extremely stiff competition with mostly 6 Stars leading the race. Just due to the sheer amount of damage that those 6 Stars do.

  • [Ceremonious] buff is only 3 percent and without many characters with Bullets, I just can’t see how you can get the effects to become extremely impactful.

Ratings

Similar in function to J, Duncan provides a slew of counters with additional effects based on his [Bullet] while accumulating [Ceremonious] to unleash a big Ultimate. Unfortunately, he has to compete with absolute damage monsters in the higher ranks, and as a 5-star he simply doesn't compete as well (though better than most!).

Psychubes
Comments

“Outside the City” is great for Mr. Duncan because his FUA is single-target and he really wants to crit. The large amount of Crit Rate on this psychube will make Mr. Duncan's [Bullet] and Moxie generation much more consistent. A good option for a [Bullet] support build.

“Luxurious Leisure” is better for a DPS Mr. Duncan build. He already has [Ceremonious] stacking in his kit, so the Ult-based gameplay of “Luxurious Leisure” works well.

“Thunderous Applause” is a decent option for getting consistent crits on Mr. Duncan. While his Skill 1 is mass, his Ultimate and FUA can trigger the Crit DMG passive. “Brave New World” is an alternative option to “Luxurious Leisure” for Ult-based Mr. Duncan builds.
