Berserker

Berserker is one of 's aura Battle Arts in Xenoblade Chronicles. It amplifies his physical damage given and received, as well as giving his auto-attacks and Mad Taunt an area of effect.

Overview
Berserker is the inverse of Rage. 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
The range of the added area of effect for auto-attacks and Mad Taunt is not known. It is believed to be similar to that of Hammer Beat (i.e. a 2m radius around the target).
