Primal Roar

Primal Roar is a rare active lord ability exclusive to legendary lord Nakai the Wanderer and introduced in Total War: Warhammer II The Hunter and the Beast DLC.

It provides major melee attack and physical resistance bonuses to Nakai and nearby allies in a short radius over a short period of time. It comes, however, with a significant drawback in that it also grants the rampage! status to all units affected.

It has a major cooldown and can be used infinite times.
