Game Mechanics: Warrior Berserk

[Gorgetrapper]

This came from the Kunark Strategy Guide, so if anything, I'm pretty sure it's fairly accurate.

Berserking
Berserking is an inherent
skill for Warriors. You can
not train in it or select it
for use. If you are seriously
wounded, it activates
automatically, causing you
to fight with greater ferocity.
Once you drop to 30% of
total hit points you become
berserk and stay that way
until you zone or are healed
to 45% total hit points.
