In Mafia Wars, a player's stamina represents how often a player is able to engage in combat. Stamina is used for fighting ,Robbing and bounty hunting other players.

Stamina Timer
By default, 1 point of stamina is replenished every five minutes. If you have the Chainsaw Bayonet from mastering the Hitman job tier, you recover stamina thirty seconds quicker.

Leveling Up
It only takes one Skill Point to gain one point of stamina permanently. Previously, it used to require two points.
