Phase tells, counters, and recommended loadouts for story bosses across Tenebrous Isle.
Community-reported · May 2026
Full phase guides below cover Thorne, The Duchess, Nox’s Beast, Madd House, and Midden. Additional island bosses are listed at the bottom as work-in-progress entries.
Thorne
Ossex · Medium · Sidearm: Mace

- Phase 1 — Trident strikes
Pattern: Swift trident blow into a tracking three-hit combo; drops delayed bombs along his path.
Tell: Quick trident wind-up; combo tracks your movement; bombs drop as he moves.
Counter: Stay near arena edges to escape bomb chains. Short burst damage so you can disengage.
- Phase 2 — Tornado burst
Pattern: Summons a ring of tornadoes that expand outward.
Tell: He stops moving to channel the swirl.
Counter: Use Hollowing — burrow underground as the ring expands.
- Phase 3 — Escalated dash + tornadoes
Pattern: Longer dash, three hops, then tornado burst again at higher intensity.
Tell: Dash path visibly extends; three hops precede the tornado summon.
Counter: Reposition early for the dash; burrow the follow-up tornadoes. Keep attacks short.
The Duchess
Queensbury Crypt · Medium · Sidearm: Daggers

- Phase 1 — Stone statue
Pattern: Wide horizontal swing across the arena; jumps on floor plates that fire ground arrows.
Tell: Wind-up before the swing; jump telegraphs arrow lanes.
Counter: Burrow on swing wind-up. Stay above or below — arrows break on her body if she blocks your lane.
- Phase 2 — Tentacle reveal
Pattern: Faster swing into immediate lunge; tentacle slams burst 3–6 times at your position; arrows persist.
Tell: Quicker swing wind-up; lunge follows instantly; ground-burst tracks your position.
Counter: Keep moving in one direction to outrun bursts. Burrow through arrows; favour ranged sidearms.
Nox's Beast
Nox's Bayou · Hard · Sidearm: Daggers · Pit Preserver trinket

- Main phase — water arena
Pattern: Bounces, poison bubbles, stomach suction mouth, ground slam sending expanding wave rings; destroys shallow water into pits.
Tell: Short hop before each bounce; second mouth opens for suction; slam precedes rings.
Counter: Dodge bounces; stay at range for suction. Jump wave rings — burrowing does not block them.
- Low health — swimming
Pattern: Swims diagonally through water, carving deep pits and damaging on contact.
Tell: Submerges and charges diagonally.
Counter: Burrow in the opposite diagonal to avoid the swim path and fresh pits.
Madd House
Septemburg (Kindlewood) · Medium · Stay below or to the sides — never above

- Phase 1 — Awakening
Pattern: Awakening animation on entry; attacks largely from above with awkward hitboxes overhead.
Tell: Opening awakening animation — free hit window.
Counter: Land early hits during awakening. Burrow to sides or below — never fight from above.
- Phase 2 — Bombs (low health)
Pattern: Throws bombs that blanket the arena for area damage on explosion.
Tell: Bombs begin appearing across the arena.
Counter: Move to a safe spot, wait out explosions, then resume from sides/below.
Midden
Queensbury Crypt (Ancestral Chamber) · Easy · Optional secret fight

- Single phase
Pattern: Secret optional encounter — single phase, Easy difficulty.
Tell: Provoke with the insult dialogue option after opening the chamber door.
Counter: Bring two Plasma Vials to reach the chamber; treat as a bonus trinket run.
