Level 30 Cooking is required to cook bream, and up to two bream can be cooked with a single action, with the chance depending on the player's Cooking level. Players will never burn bream.
The amount of Hitpoints restored is 1/3rd of the player's Cooking level or Fishing level, whichever skill is the lowest.
When leaving Neypotzli, this item is removed from the player's inventory with the message: The resources from Neypotzli fizzle to dust as they are severed from its magic.
At 20 fishing, the first level you can fish for raw bream, you heal 7 hitpoints instead 6. This is the only case where the healing of the cooked bream rounds up instead of down.
