Stamina

Stamina is a feature in the game that allows you to run but with a limit before leaving you to rest and disable the average walking speed and enable half of your original speed without any boosts once you've used up all your stamina. It can be used up by running, flying, using weapons (very low amount but most with guns) and using mana related items. You can also get more stamina balls in your screen by using Stamina Crystals. Like healing potions there are energy potions like the Lesser Energy Potion, Energy Potion and the Greater Energy Potion.
