Whirlwind Attack is a high-level class ability which can be used by 'warrior-type' classes: barbarians, fighters, monks, paladins and rangers. It can be selected only after reaching level 20 for fighters and 18 for rangers.
Whirlwind Attack raises the melee attack rate of the user to 10 for 1 round, but it also gives a penalty to THAC0 and damage of -4.
