Stamina is one of the Attribute stats in Hellpoint.
Function
Stamina is governed by stamina points, which determine how many times a player can attack, sprint, dodge, or block without pausing. Stamina regenerates over time when not performing a function that consumes stamina. When all stamina points are used, the player will be unable to perform these functions. Attempting to block without any stamina points will result in a broken guard and momentary stun.
Attempting to use smaller amount of stamina than required will be successful if you use it to attack, jump or dodge.
Upgrades
Stamina can be increased by leveling the attribute with Axions. Also there are buffs from some kinds of weapon.
