Stamina

Stamina is a status in the game that allows players to sprint. Stamina regenerates at the rate of 10 per second, if player does perform any actions besides walking. If stamina drops below 30, the player's movement speed starts to slow. By default, when you kill another contestant, you instantly regenerate 50 stamina, but this effect can be buffed with the Cannibal perk.
