Berserker

Berserker (, Berserker) is one of 's s in Xenoblade Chronicles. It amplifies his physical given by 75% and received by 25%, as well as giving his s and Mad Taunt a cone-shaped area of effect.

Overview
Berserker is the inverse of. It's for when Reyn thinks that the extra damage he's about to deal will eclipse the extra damage he's about to take, which is likely because the strength increase is far more powerful than the defensive drop. The main risk is that something big happens while he's vulnerable, because 25% is not chump change. That said, he can always switch to another aura if he needs to.

Additional data
While Berserker is active, the range of Reyn's auto-attacks and Mad Taunt changes from "single target" to "cone of 120-degree angle", hitting everything within the move's normal max range.
