Quick answer
Avoid the hammer slam, then break the cracked hammer and attack the exposed fin. Build the Power Egg gauge during the debris-and-beam defense interval and use the Drill Attack. The second phase exposes a chest weak point after the tilting beam; the final phase requires breaking the hammer and chest zones back-to-back before the main damage window opens.
Major spoiler warning
This page reveals the Coohla Temple boss, all three phases, and the route into the final story encounter.

Prepare for the fight
- Keep enough ink and Gadget charges to punish a newly cracked weak point.
- Watch warning zones on the floor and the shadows beneath falling debris.
- Stay close enough to reach the destructible zone after an attack finishes, but do not stand inside the impact area.
- Preserve a reliable movement lane for the rotating and tilting beam patterns.
Phase one: break the hammer
Desshurt opens with a hammer slam. Clear the impact zone, then attack the cracked hammer before it recovers. Breaking it exposes the fin behind the armor. Shift fire to that fin while the shield rebuilds. The safest damage comes after the slam; spending resources before the hammer cracks wastes the short opening.
Defense interval: debris, Salmonids, and beams
After the weak-point sequence, falling debris and a rotating beam pressure the arena while supporting Salmonids appear. Use their Power Eggs to fill the gauge and trigger the Drill Attack. Check the ground and overhead shadows before stopping to fire. A movement-oriented Showstopper can help clear enemies and collect eggs without remaining inside one beam lane.
Phase two: expose the chest
The next main attack uses a tilting beam before Desshurt lands on its chest. Move clear of the beam and final impact, then attack the cracked chest zone. Break it, use the resulting weak point, and complete the next Power Egg and Drill cycle.
Phase three: break both zones
The final phase combines the earlier mechanics. Avoid the hammer and chest attacks, then break both destructible zones in succession. Do not spend every resource on the first break if the second zone is still protected. Once both are down, commit the saved weapon, Gadget, and Showstopper damage to the exposed boss.

Route steps

- 2Survive the defense intervalAvoid falling debris and the rotating beam while defeating Salmonids for Power Eggs, then trigger the Drill Attack.
- 3Open the chest weak pointMove clear of the tilting beam and final impact, then destroy the cracked chest zone and use the resulting opening.
- 4Break both final zonesIn the last phase, destroy the hammer and chest zones back-to-back before committing saved damage to Desshurt.
If the fight keeps going wrong
If the weak point closes before enough damage lands, begin each attack with a full ink tank and stop firing at protected armor. If debris is causing most of the damage, keep moving while reading shadows instead of watching only the boss. During the final phase, treat the two destructible zones as one combined task and preserve enough resources to finish both.
