Frozen Berserker
( Frostburn, p. 48)[General]
When you enter your barbarian rage, your body becomes infused with cold energy.
Prerequisite
Ability to rage,
Benefit
As long as you are under the effects of a barbarian rage, you gain the cold subtype. You gain immunity to cold, but have vulnerability to fi re, which means you take half again as much (+50%) damage as normal from fi re, regardless of whether a saving throw is allowed, or if the save is a success or failure.
