Quick answer
Ride the opening surfboard above the rising tide, then Bot Hop between the floating platforms. On each main platform, clear Salmonids and Power Egg orbs to charge a Drill Attack for one Salmonarch head. After all three heads fall, follow the timed route back to the Hideout Ship and operate the crane.
Major spoiler warning
This page reveals the main-story final boss, the complete encounter structure, and the post-credits unlocks.
Fight priorities
- Look downward before committing to a Bot Hop so the landing stays visible.
- Clear dangerous support Salmonids before chasing Power Egg orbs.
- Preserve an escape route for the sweeping beam instead of attacking from an exposed platform edge.
- Treat each head as a separate cycle: reach the platform, build the gauge, use the Drill Attack, then move.
Phase-by-phase route
The encounter begins as traversal rather than a normal damage phase. The route card separates the rising-tide approach, the three Drill Attack cycles, and the ship finish.
