Usage:
whirlwind

The warrior 'whirlwind' skill is used only in melee combat with multiple
opponents.  When you start your whirlwind attack, you'll skip from
target to target, hitting targets at random in quick succession.

Weapons with a flexible damage type, such as whips and flails, can
strike additional times.
