Ascend
Ten towers in three bands, each a climb of short rooms with a boss in the last one — and three difficulty tiers to master.
Normal · Hard · Nightmare
Every tower can be climbed on three tiers. Higher tiers make enemies tougher and loot better.
| Normal | Hard | Nightmare | |
|---|---|---|---|
| Enemy health | ×1.0 | ×1.4 | ×2.2 |
| Enemy attack | ×1.0 | ×1.4 | ×2.6 |
| Enemy speed | ×1 | ×1.05 | ×1.1 |
| Gold / XP | ×1 / ×1 | ×1.35 / ×1.35 | ×1.8 / ×1.8 |
| Loot item level | — | +2 | +4 |
| Rarity weights | — | Common ×0.5 | Common ×0, Uncommon ×0.5 |
| Elite affixes | — | 1 | 2 |
| Extra waves per room | — | — | +1 |
| Room modifier chance | 30% | 50% | 100% |
Clear a tower on Normal to unlock Hard, then Hard to unlock Nightmare.
