Épreuve Extrême

Extreme Trial is a key-gated dungeon with both a solo and a team mode, unlocking at Account Lv.4. You spend Extreme Trial Keys to attempt it, and clear as far up its difficulty ladder as your roster can handle.

The ladder is longer than it looks

Extreme Trial’s difficulty ladder runs 200 stages deep, grouped into named difficulty brackets (you’ll see labels like “Lv.20”, “Lv.40”, and “Lv.60” as you climb). It’s easy to assume the ladder stops at whatever bracket you can currently reach, but the data defines stages well past that — there’s a long runway ahead as your account and roster grow. Rewards land every 5 stages the whole way up, not just at the named bracket boundaries, so there’s no reason to stop pushing once you’ve cleared a named tier.

How to play it well

Push as far as your current roster can clear rather than stopping at the first named bracket you unlock — since rewards land every 5 stages, partial progress into the next bracket still pays out. Extreme Trial’s team mode shares the same difficulty ladder as solo, so a build that clears well solo is a good sign for how far you’ll get in team runs too.
