Tinker Tools

A rare trinket that applies a status effect at the end of each battle via StatusOnBattleEnd. Tinker Tools rewards winning fights — surviving a battle triggers a persistent status that carries into the next encounter, providing inter-battle benefits that compound over longer runs. Strong in builds focused on endurance and run progression rather than single-battle burst.

StatusOnBattleEnd fires once per completed battle, meaning you need to survive to the end of the fight to collect the effect. Unlike on-hit or on-damage triggers, this is reliable and not subject to RNG timing within combat — it simply fires on victory. If the applied status is a buff (like a stat boost or regen), Tinker Tools effectively gives a free bonus every floor. If it's a debuff applied to enemies, it would fire between encounters rather than during them, which is unusual and would likely carry into the next battle start.

Strongest on builds that clear fights consistently and want to maintain sustained buffs across the entire run. Pairs well with items that interact with statuses you already have (like AmplifyStatus or conditional bonuses based on active effects). Less impressive in builds that end fights quickly without needing inter-battle sustain — the end-of-battle timing means Tinker Tools adds no in-fight power whatsoever.
