Bloodthirsty

 is a hero personality.

Initial acquisition
During the random event Family Feud, if the ruler sends the two feuding heroes to the Bossadome to fight, there 25 percent chance the first of the two heroes gains this personality after killing the other.

Mechanics
After a hero with this personality scores a kill, they gain a stack the Bloodthirsty buff. All stacks expire at the same time: three turns after the most recent kill. Put another way, each new stack refreshes the duration of previous stacks.

The buff applies a multiplier equal to 100% plus 10% per stack to Strength, Intelligence, and Dexterity.
