Ration

Typically found in crates or barrels lying around the dungeon. Rations heal 10 hp slowly over time. They are never used as an autoheal, and are mostly useful for keeping the player's HP up between encounters.
 * You can combine them with a flask of poison blood to create an antidote.
 * They are more cost efficient than potions (at least until you have used 4 life potions) at which point potions are just as efficient. So, if you you buy 3 life potions at the starter shop, sell those rations and buy healing potions instead. If you don't buy life potions, you are better off selling the healing potions and buying as many rations as you can. In summary 4 rations are cheaper and heal more than a healing potion.
