Smash

Smash is a druid skill that does damage to the target with total 
disregard for their armor.  Smash requires the druid to be in
dire bear form.  Smash deals 1/12 of the victim's max hit
points in damage, and costs 1/24 of the user's max movement points. 
Smash is usable once per round.

The classes that get the skill smash are:

druid      : Level  75 (excellent)
