During Setup, a unit with the Bounty keyword chooses an enemy
or
unit. The chosen unit gains a bounty token. After an allied unit with the Bounty keyword defeats an enemy unit that has one or more bounty tokens with an attack or effect, the allied unit’s controlling player scores 1 VP.If the unit with the Bounty keyword defeats a unit with a Bounty token but is defeated during that attack as a result of some other effect, such as the Deflect keyword, the player will NOT score a VP, as the attacker is defeated during Convert Defense Surges step, prior to resolving the Bounty keyword.[Source]
