Mimic Chests in Lineage Piece (25% Spawn, 2x Drops)
How Mimics Work
Per the official Trello, treasure chests spawn across the islands, and opening one has a 25% chance to spawn a Mimic instead of paying out immediately. Kill the Mimic and the chest’s rewards roll at double (2x) drop chance.
That flips the usual instinct: a Mimic is the best outcome of a chest, not a trap to avoid.
What Chests Drop
The chest pool is Coins, Gems, Rerolls and Odd Tomes. The Odd Tome is the chase item — it summons the Frieren boss at the Elysian Summoner — and Mimic-doubling is the fastest way to stack Tomes.
Farming Notes
- Chest spawns are server-shared: sweep an island, then server-hop rather than waiting on respawns (island list).
- Mimics are a fight, so bring your damage kit on chest runs — a Mimic you can’t kill is a doubled reward you don’t collect.

Expected kills = 1 ÷ (rate ÷ 100), rounded up — the average run length for one copy; half of all players need more than that. Source: official Lineage Piece Trello board (export dated 2026-08-24). Rates are the board's listed values; "expected" = 1 / rate, the average number of kills for one drop, not a guarantee.
