Midden Boss Guide for Mina the Hollower

Summary

Midden is an optional Queensbury boss hidden behind the Ancestral Chamber's Plasma Vial gate.

The fight starts only if you choose to push through the door, so it works best as a controlled side objective rather than a surprise detour.

Expect a compact arena and enough pressure to punish sloppy approach routing.

This encounter sits behind a two-Vial door and rewards players who are comfortable spending resources for optional content.

Use this page before first attempts on Midden, then return after a few pulls to refine punish windows.
Pair it with a defensive setup if you are still learning movement, or a damage setup once the pattern is familiar.
Use the notes as a route checkpoint when deciding whether to spend Bones before continuing.
Treat the first few attempts as scouting pulls: learn one safe answer per attack before chasing full damage rotations.
If the fight blocks progression, favor repeatable survival over a faster clear; route consistency is the value this page should protect.

Fight notes belong with Queensbury Crypt, especially the Ancestral Chamber route.
This boss is better treated as a local route gate than a standalone DPS check.
Reward context: Fly Bait trinket.

Test safe openings first: one attack, reposition, then repeat until the recovery window is obvious.
Watch for room hazards and approach lanes before judging the weapon matchup.
Keep exact damage numbers flexible because patches, upgrades, and modifier settings can change the feel of the fight.

Greeding long combos after the first safe hit instead of resetting spacing.
Entering with a route loadout when the fight needs a boss-specific defensive or damage setup.
Ignoring the nearest Underlab and losing resources to repeated runbacks.
Changing too many loadout pieces between pulls, which makes it harder to tell whether the improvement came from routing, spacing, or raw stats.
