Medkit

The First Aid Kit is a item in Risk of Rain that restores one's health by 10 HP after being hit after a short delay. If one is hit, then hit again, the heal from the first hit is cut off and only 10 HP will be healed.

Tactics
Note: The Glass artifact, which reduces your health drastically, makes this item especially invaluable.

Trivia

 * This item can be dropped from the cabinets in the Medical Bay in Risk of Rain (Level).
 * In the game, the item's name is incorrectly written as "First Aid Kit".
 * The address listed in the Shipment Details is 9119. 911 is the emergency telephone number for parts of North America, which fits with the Medkit's theme of emergencies.
