Union (Guild) System

Unions are the guild system in Etheria: Restart. They allow you to play together with your friends, chat with them more easily, tackle dangerous bosses together and earn some great rewards! Joining a Union is very important, as you will miss out on a lot of resources if you won't - but don't be afraid, it's not time consuming. Also, creating a Union is fully free - which is something different compared to most gacha nowadays that require premium currency to be used to create one.
Sadly, Unions are limited to 30 players and even if the Unions is leveled up, the cap doesn't change.
Check In

Make sure you and your Union-mates login daily, as the amount of resources you will obtain every day will increase the more players in the Union play the game daily!
Weekly Tasks

Weekly tasks reward you with Union EXP and a plethora of resources, including summons, stamina potions, coins and more! The tasks aren't that hard to do and you most likely will complete each one by just playing the game normally.
Keep in mind that the reward track and the tasks reset every week (as the name suggest, but it's worth mentioning)!
Anchor Recon

Anchor Recon is the boss-fighting mode dedicated for Unions. There are 3 variants of a single boss available, each with different elements and mechanics, so you have to adapt your team in order to deal as much damage as possible to the boss. This will affect the rating you will receive (ranged from D to SSS), how much energy of the boss you will reduce and then the rewards you will obtain.
On top of the rewards tied to the rating, there are additional rewards for reducing the energy to certain levels (and killing the boss). Each boss has different max energy - 2000, 3500 and 5000 - and different breakpoints for the cumulative rewards.
Also, you can place up to 3 characters you possess on the Union Support list and your Union-mates will be able to use them in their battles. And in return, you will obtain Union Coins!
Currently there's no limit how many times you can challenge the boss daily, but only your highest score counts for the ranking rewards and progression towards reducing the boss total energy. We're not sure if this is a beta-only thing, allowing us to test stuff easier or it will stay this way for the full release.
Union Shop

The Union Shop holds even more resources that make joining an active Union very important - you can buy them using Union Coins that you obtain from Weekly Tasks, Check In and Anchor Recon. Most of the better resources are locked behind Union Levels though!
Similar to the Weekly tasks, the Union Shop also resets on a weekly basis.
We will soon add a dedicated guide to show what you should prioritize when buying things from the Union Shop!
Union Assistance

Union Assistance allow you to slowly obtain characters - including the SSR Characters!
Every day, you can select a character you want to obtain and you Union-mates can use their Data Meme to fullfil request (4 Data Memes of matching element are required). You will obtain a character fragment in return and you need to gather 50 to get a copy of that character. So it takes roughly 1.5 months to obtain one copy - it's quite long, but hey, it's free!
Keep in mind that you're not able to request Light/Dark characters here - only the Red/Blue/Green ones are available.
United Front - Union vs Union
This feature isn't available in the game yet, but we know it's PVP between two Unions. It also won't be available on the game's launch and there's no release date yet - outside of 'some time after release'.
