Combat Phases & Tactics Breakdown
P1
Magma Shield & Geyser Surge (100% - 70% HP)
Protected by three molten crystal nodes on its dorsal ridge, making the main body impervious to damage.
Enemy Attacks to Watch For:
- Boiling Lava Spray (Covers 50% of the arena in lava)
- Sonar Shockwave (Disrupts HUD and slows player movement)
Tactical Counter:Focus all fire exclusively on the 3 glowing purple crystal nodes on its back. Destroying all three shatters its lava shield.
P2
Caldera Breaching & Meteor Shower (70% - 30% HP)
The whale breaches completely out of the boiling lava lake, calling down volcanic meteors from the sky.
Enemy Attacks to Watch For:
- Caldera Meteor Rain (Marked red circles on ground)
- Tail Tidal Wave (Massive wave of boiling magma)
Tactical Counter:Sprint between safe platforms using grapple/jump timing. Fire high-explosive rockets into its glowing exposed throat.
P3
Hyperbeam Core Meltdown (30% - 0% HP)
The final desperate enrage. Charges a continuous nuclear laser beam from its mutated blowhole.
Enemy Attacks to Watch For:
- Nuclear Blowhole Hyperbeam (Instant kill if touched)
- Ground Shatter (Destroys outer stone platforms one by one)
Tactical Counter:Circle-strafe behind its turning radius. Unleash your full arsenal (grenades, sniper rounds, full-auto rifle) into the glowing radioactive core until defeated.
