Quick answer

Find the fight, then tune one part of your build

Use the lookup first to confirm the route, reward, and threat level. If a fight keeps killing you, change one thing at a time: safer weapon, ranged sidearm, more healing room, or a trinket that solves the arena.

  • Search by boss name, reward, region, or recommended item
  • Filter secret bosses, mandatory bosses, rewards, difficulty, and spoiler level
  • Check the secret boss section when you only need optional rewards
  • Use the notes column when a location or route can vary

Reward
Blinking Glass Trinket.

OptionalVery HardHealth
Region / location

Reward

Reward
Gilded Rod upgrade.

Player note
The arena is tight, so attack only after the weak point is exposed. Dodging waves matters more than trading hits.

Before another attempt

Boss prep that fixes most stalled runs

Mina bosses punish repeated panic more than one bad build. Change one variable at a time, then learn the pattern with enough healing and space to survive the next phase.

Weapon

Default to safe reach

Nightstar is the safest first-pass weapon for most players because it lets you learn tells without standing inside the hitbox. Swap to daggers only when you already know the openings.

Sidearm

Bring ranged answers

Ranged sidearms help during second phases, water arenas, flying targets, and any fight where the boss punishes close trades. Refill Joules before entering the room.

Trinkets

Use survival before damage

Proto Spark, defense, movement, and fight-specific utility usually beat pure damage while you are still learning. Switch to burst once the pattern is readable.

Secret bosses

FAQ

Quick Answers

How many bosses are in Mina the Hollower?

The game has more than 25 unique bosses and mini-bosses. This hub focuses on fights with enough clear route, reward, and prep information to help you plan your next attempt.

How many secret bosses are there?

The currently cross-checked secret boss set has nine: Midden, Maxi, Armand, Dugin, Willis, Dark Deluxy, Mirren, Evra the Undying, and Thalassion.

Which secret boss should I do first?

Midden is the best first secret boss to check because he is found in Queensbury Crypt, is less demanding than later hidden fights, and rewards Fly Bait before The Duchess.

What should I change if a boss keeps killing me?

First add survival: more healing room, Proto Spark, defense, movement, or a safer weapon. Then learn one attack string at a time and only switch to high-damage setups when the fight is readable.

Is there a separate page for each boss?

Not right now. Use this hub to search the covered fights, compare rewards, and jump to the boss section you need from the table or mobile cards.
