Anime Adventures Eren: Unit Overview
Eren, known in-game as Usurper (Founder), is a Mythical-rarity hybrid summon unit and one of the most iconic meta picks in Anime Adventures. He is obtained by evolving the base Usurper unit, and he stands out as the most expensive unit in the game — 100,000 yen to deploy, and roughly 1,050,000 yen when fully maxed. His power comes from the Rumbling: an active ability that floods the map with Wall Titans that damage both flying and boss enemies.

Here is how Eren's core deployment stats look at Level 1 versus Level 100:
| Stat | Level 1 | Level 100 |
|---|---|---|
| Deployment Cost | 100,000 yen | 100,000 yen |
| Tower Type | Hybrid SUMN, None | Hybrid SUMN, None |
| Range | 10 | 12 |
| Spawn HP | 10,000 | 92,040.65 |
| Active Attack | eren_final:rumbling | eren_final:rumbling |
| Ability Cooldown | 480s | 480s |
Eren's damage scales with HP, not traditional attack stats. Stacking Max Stats into damage percentage also inflates his HP pool, which is what the titans and Eren himself deal damage from.
The Extinction Ability & Upgrade Path
The Extinction is Eren's signature active. When triggered, he spawns 10 Wall Titans plus 1 Usurper (Founder). Every spawned titan is capable of damaging flying and boss enemies, which makes Eren exceptional for wave defense and long infinite modes. The ability runs on a 480-second cooldown, with duration varying based on enemy HP and timing.
Each upgrade dramatically increases the HP that Eren spawns with:
| Upgrade | Cost | Spawn HP (Level 1) | Spawn HP (Level 100) |
|---|---|---|---|
| Deployment | 100,000 yen | 10,000 | 92,040.65 |
| Upgrade 1 | 150,000 yen | 25,000 | 230,101.63 |
| Upgrade 2 | 300,000 yen | 50,000 | 460,203.25 |
| Upgrade 3 | 500,000 yen | 100,000 | 920,406.5 |
Boss Melter
- Titans hit boss enemies
- Sustained Rumbling pressure
- Strong in Albireon runs
Anti-Air Coverage
- Titans damage flying units
- Covers a common weakness
- Great hybrid filler
Farm Dependency
- Needs gold farms to max
- High upfront deployment cost
- Rewarding when fully built
Eren is the most expensive unit in the game. Bring dedicated farm units and expect extended AFK gold farming sessions — roughly 30 minutes per major upgrade chunk in practice.
Step-by-Step: Building Max Eren
Evolve Usurper
Obtain the base Usurper unit and gather the required evolution materials to unlock Usurper (Founder).
Set Up Farm Units
Deploy your gold farm units first. Eren needs roughly one million yen total to reach max, so farming comes before summoning.
Roll for Traits (Optional)
Use rerolls to chase the Unique trait. Positioning near the star markers in the lobby and watching for the pink crown indicator is a popular reroll routine.
Deploy and Upgrade
Place Eren early, then feed upgrades as gold accumulates: 150k, then 300k, then 500k. Each stage multiplies his spawn HP.
Trigger The Extinction
Activate the Rumbling against boss-heavy waves. The 480-second cooldown means timing matters — save it for high-HP threats.
A fully maxed SSS-stat Eren can deal damage in the tens of millions per Rumbling cycle when his HP pool and all 10 titans are accounted for, keeping him meta-relevant in Albireon and infinite content.
Stats, Traits & Curse Mechanics
Understanding which stats actually matter on Eren saves serious reroll currency:
| Stat | Priority | Notes |
|---|---|---|
| Damage % | Highest | Also inflates HP pool; the core stat for SSS builds |
| HP | High | Directly feeds titan damage output |
| SPA | Low | Does not meaningfully affect his ability loop |
| Range | Low | Titans do the work; base range of 10-12 is sufficient |
His curse stats also deserve attention. A negative SPA curse (around -8.7%) can actually be beneficial because it reduces his ability cooldown, letting The Extinction come back faster. Negative damage on a curse appears to have little practical effect on him since his damage derives from HP.
A minus SPA curse lowers Eren's ability cooldown. Don't panic-reroll a curse that looks negative — check whether it reduces SPA before spending remnants.
As of Update 19.0.0, Usurper (Founder) is unobtainable through his raid, which was removed. Trading with other players is currently the main acquisition path. More details on the Anime Adventures Wiki.
