Etheria: Restart Union Guide
Clans, guilds, and alliances—no great RPG is complete without them. And in Etheria: Restart, they’re not just present—they’re essential. Whether you’re looking to rack up rewards, flex your PvE muscles, or just play alongside your friends, Unions are your all-access pass to a better gaming experience.
In this guide, we’re diving into everything you need to know about Unions in Etheria: Restart. From daily rewards to crushing massive bosses, we’ve got you covered. Let’s jump right in!
What Are Unions in Etheria: Restart?
Unions are your go-to group system—think guilds with a sci-fi twist. You can join a friend’s Union or set up your own completely free. No premium currency, no complicated setup. Just a few clicks and boom—you’ve got yourself a home base for teamwork and rewards.
Each Union can hold up to 30 players, and that cap doesn’t budge no matter your level. That means it’s crucial to join an active Union. Dead Unions = dead rewards. So don’t let Johnny and his four AFK cousins drag you down—join a crew that shows up.
Daily Check-In Rewards: Free Stuff for Just Logging In

Let’s start with the easiest win: daily check-ins. Every day, each member can “check in,” which contributes to a pool of rewards for the whole Union. The more check-ins, the more loot everyone gets.
Here’s what you can snag when 25 members check in:
- 450 Stamina
- 700 Union Coins
- 12 Supply Packs (random Etherons!)
- 180 Union XP
So even if you’re on vacation, take 30 seconds to log in and hit that check-in button. Your team will thank you—and your future self will too.
Weekly Tasks: Progress Just by Playing

Weekly Union tasks are the kind of challenges you complete just by playing the game. Think defeating bosses, burning stamina, and doing your regular grind. Easy.
Here’s what’s in it for you:
- Etheria Coins
- Union Coins
- Training Data
- Hydra Crystals
- Stamina
- Reconfig Chips
- Investigation Records
That’s not all. Completing tasks adds Co-op Points and Union XP, which contribute to a long-term reward track. We’re talking:
- Summons
- Shadowprints
- Advanced Supply Packs
- And much more!
Long story short: play the game, complete your weeklies, and you’ll rake in rewards over time without even trying.
Union Bosses: Big Fights, Big Flex

Here’s where things get serious—and seriously fun. Union Bosses rotate between three types:
Each boss has its own mechanics and elemental twist. We’ve got detailed guides for each (check out our boss strategy section for a deep dive), but here’s a quick rundown on how scoring works:
You fight to reduce the boss’s HP, starting from 100 and trying to get it to zero. Your score rank is based on how much damage you do:
- D: 0–9
- C: 10–19
- B: 20–29
- A: 30–39
- S: 40–59
- SS: 60–79
- SSS: 80–100
Hit 100 and you’re top-tier with a Triple S score. Oh, and here’s the kicker—you can fight as many times as you want. Only your highest score counts.
The boss has 2000 energy, and that’s what your Union needs to fully deplete to earn every chest. Rewards drop at:
- 200 Energy – Purple Shadowprint
- 600 Energy – Advanced Investigation Records
- 1200 Energy – Advanced Supply Pack
- 1800 Energy – Mental Stabilizer
- 2000 Energy – Hydra Crystals (final “kill chest”)
All chests also give Etheria Coins and Union Coins. So even if your Union can’t go all the way just yet—get as far as possible for those juicy drops.
Union Shop: Don’t Spend Too Soon!

Got a mountain of Union Coins burning a hole in your digital pocket? Hold your horses. The Union Shop rotates every 7 days and unlocks better items as your Union levels up.
Pro tip: Wait until the last 24 hours before reset to spend. Your Union might level up just in time to unlock better rewards.
Here’s what you can buy (depending on Union level):
- Summons
- Perfect Lattice Fragments
- Etheria Coins
- Red Shadowprints (at Union Level 10!)
Strategic spending = maximum value.
Union Assistance: Help Your Friends, Get Free Heroes

Want to farm fragments for your dream hero? Union Assistance is your best friend. Here’s how it works:
- Choose a hero (Hollow, Odd, or Reason only).
- Use Data Memes of the same element to request fragments.
- It takes 4 Data Memes per request, and your Union mates can contribute.
- Once you gather 50 fragments, you get the full hero.
Yes, it takes time (around 6 weeks on average), but it’s completely free. You earn Data Memes from:
- Check-ins
- Weekly tasks
- Wyrm boss chests
If your Union is active, you’ll get that SSR sooner than you think.
What’s Next for Unions?
Right now, the rumor mill is buzzing about Union Battles—PvP-style matchups between Unions. While it’s not in the game just yet, the devs have hinted at its arrival. When it drops, you can bet we’ll have the full scoop.
Final Thoughts
Unions in Etheria: Restart aren’t just optional—they’re essential. Whether you’re here for the loot, the community, or the sheer joy of toppling Wyrms with your crew, there’s no better way to elevate your gameplay.
So join a Union, check in daily, complete your weeklies, and smash those bosses. You’ll be swimming in rewards—and having a blast while doing it.
