Kilnroot Colossus is a bruiser treant miniboss. At the lowest Threat it has 940 health, hits for 30 and carries 10 armor. It moves at 3, can reach you from 2.6 away, and telegraphs each swing for 13 ticks before it lands, then waits 26 before the next one.

It fills the Miniboss slot in Cragmaw Deep.

Killing it pays 80 XP, and it drops something 50% of the time. Crowd control lands on it as resistant.
