All Bosses — Full List & How to Beat Them

Mina the Hollower features around 28 distinct bosses and mini-bosses. Six of them guard the failing Spark Generators across Tenebrous Isle — and you can tackle those regions in almost any order. On top of those, nine secret bosses are tucked behind side quests and hidden prerequisites, each handing out a trinket or upgrade.

Every boss follows the same rhythm: read the tell, dodge with Hollowing, and punish in short bursts. The fights below are the ones with the deepest, most-searched strategies — start with Thorne, the first boss.
