The Colossal Hydra is a superior variant of the hydra. It has a chance of spawning after purchasing the unlock Bigger and Badder for 150 Slayer reward points from any Slayer master.

In combat, the Colossal Hydra will occasionally shoot out an electric lightning attack. The lightning will come as two pools chasing the player for some time, dealing modest damage if struck.

Drops

In addition to 100% drops and tertiary drops, superior slayer monsters will always roll 3 additional items, of which only 1 roll may be from the superior unique table. The other rolls are performed on the regular counterpart's table; their displayed drop chances represent a single roll.

Drop rates estimated based on 16,739 kills from the Drop Rate Project, unless otherwise cited.

The average Colossal Hydra kill is worth 254,137.44.

The average Colossal Hydra kill while on a Konar task is worth 256,183.9.
