Cleave

Requires: Forceful Blow
Time Required: Free Action

Dropping your first target propels you into the next. If you reduce a creature to zero Stamina with a melee or unarmed attack, you may immediately make a basic attack of the same sort against any creature within your reach and adjacent to the target you dropped. Once you use this ability, you cannot use it again until the start of your next turn.
