Jarate, the "Jar-based Karate", is an unlockable secondary weapon for the Sniper. It is a standard glass mason jar filled above half-way with the Sniper's urine, capped with a screw-on lid.
The item is a thrown weapon; the jar breaks and the liquid is splashed over a short distance, either upon immediate contact with the world or another player. Enemies caught within the 200 Hammer units splash radius will be covered in the contents of the jar for 10 seconds. During this period, all incoming damage is registered as mini-crits. The victim's view is tinted a watery yellow, and they shed yellow droplets. The effect duration can be reduced through continuous healing, or can be removed instantly by jumping into water or touching a resupply cabinet. This weapon normally has a 20-second cooldown before it can be used again as indicated in the HUD, and a ding will play to alert the player it has regenerated.
