Mina the Hollower Bosses — All Bosses Ranked & Strategies
Updated 2026-06-02
Mina the Hollower bosses are the highlight of the game — six unique encounters with distinct mechanics, multiple phases, and memorable designs. Each Mina the Hollower boss requires pattern recognition, stamina management, and a well-chosen loadout. This guide covers every boss in encounter order with detailed strategies for each phase.
Boss difficulty ranking
| Rank | Boss | Phases | Difficulty |
|---|---|---|---|
| 1 | Drowned Matriarch | 2 | Easy |
| 2 | Grimwarden of the Grove | 2 | Medium |
| 3 | Crystal Colossus | 2 | Medium |
| 4 | Lich of the Deep | 2 | Hard |
| 5 | Hollow King | 3 | Very Hard |
| 6 | The First Hollower | 3 | Extreme |
Key boss strategies
The Drowned Matriarch is weak to electric damage — prioritize the Spark Tip whip upgrade before this fight. The Grimwarden requires fire damage from Flask Bombs during its root-summon phase. The Crystal Colossus has a stamina-draining aura; use the Grappling Hook to pull its crystal shards and create openings. The Hollow King's three phases demand mastery of all weapon types. The First Hollower alternates damage-type immunities, forcing you to rotate sub-weapons mid-fight.
Phase transition rules
All Mina the Hollower bosses transition to their next phase at roughly 66% and 33% health. Phase transitions provide a brief safe window — use it to heal and swap sub-weapons. Never use a Flask Bomb during a transition animation; the damage window closes before the explosion lands. Learning the exact timing of each Mina the Hollower boss's telegraph is the single most important skill for beating them reliably.
