The fight

Mechanics

The Hydra loses a head and changes colour at each health threshold.

For the first three phases, lure it onto a vent: green to the red vent, blue to the green, red to the blue. Phase 1 drops poison pools for up to 12 a tick. Phase 2 sends lightning from the corners that binds you and hits up to 22. Phase 3 stuns you in the middle and breathes fire to your sides for up to 25. The last grey phase needs no vent, attacks every 4 ticks and can hit 55.

Which style: Ranged, its weakest style. Melee with a dragon hunter lance also works.
