Chest ambush and Satiated
Every standard loot chest resolves one seeded 0.1% Mimic roll when the hero first enters interaction range. Boss and horned chests are protected. A fresh Mimic begins at half its maximum Satiated size and hunts the nearest reachable standard chest within 500px before pursuing the hero at any distance; each gear item or Skill Heart it consumes grants one uncapped Satiated stack. It has no Elite form and Bite is its only action.
| Movement speed | Attack speed | Damage | Size | Monster level |
|---|---|---|---|---|
| +1% | +1% | +3% | +1% per stack, capped at 200% | +1 per stack, capped at hero level |
| Stacks | Unlocked reward |
|---|---|
| 5 | All gear and Skill Hearts gain +5 item levels. |
| 10 | One additional guaranteed gear roll. |
| 15 | Each item replaces one lowest-tier affix. |
| 20 | One additional guaranteed gear roll. |
| 25 | All gear and Skill Hearts gain one rarity promotion. |
| 30 | One additional guaranteed gear roll. |
| 35 | All gear and Skill Hearts roll their maximum legal affix count. |
| 40 | One additional guaranteed gear roll. |
| 45 | All gear and Skill Hearts gain a second rarity promotion. |
| 50 | One additional guaranteed gear roll every five stacks thereafter. |
All unlocked thresholds apply together to ordinary gear and Skill Heart drops. Guaranteed bonus rolls are gear. On defeat, the Mimic becomes an automatically opening horned chest that cannot transform or be consumed; XP, gold, crafting rewards, shards, and other orbs keep their normal paths.
Bite
Mimic holds at 50% of its authored melee reach, commits to the visible strike, and can deal at most one hit. Each strike connects only when its target intersects that trail during the corresponding active frames. Moving outside the trails or waiting until their active windows have passed avoids them, while touching the monster still deals 90% of its current outgoing damage.
