The Urination System is the primary means through which piss is obtained and stored.
After drinking any liquid (Water, Potions, etc.) and waiting for 2 minutes, you will gain the Full Bladder buff. If you have a full bladder, you can sit on a toilet to piss and empty your bladder, or instead fill a Piss Bottle, Pisstcher, or Piss Vortex with piss using the crafting recipes below. If you fail to empty your bladder through one of these means, after a few minutes you will gain the Extra Full Bladder buff, followed by the Extremely Full Bladder buff. Once you have gained the Extremely Full Bladder buff, if you still do not empty your bladder, a small amount of Honey will appear on the floor and your bladder will become empty.
When piss is stored in a piss container, it can be used as a crafting resource in many different recipes, which are listed below, and can be used as ammo for several piss weapons.
