SRD:Wolverine

=WOLVERINE=

These creatures are similar to badgers but are bigger, stronger, and even more ferocious.

Combat
Rage (Ex): A wolverine that takes damage in combat flies into a berserk rage on its next turn, clawing and biting madly until either it or its opponent is dead. It gains +4 to Strength, +4 to Constitution, and –2 to Armor Class. The creature cannot end its rage voluntarily.

Skills: Wolverines have a +8 racial bonus on Climb checks and can always choose to take 10 on Climb checks, even if rushed or threatened.
