The Calorie bomb (empty) is an Invention device in the dwarven technology tree. Discovering this device requires the player to have the blueprint unlocked from the dwarven technology tree, level 60 Invention. Success in creating the blueprints earns 32,284.5 Invention experience.
It can be filled with 5 of a chosen fish to charge it and then thrown to heal players in an area of effect. Fish choices are limited to the following:
- Calorie bomb (swordfish)
- Calorie bomb (monkfish)
- Calorie bomb (shark)
- Calorie bomb (cavefish)
- Calorie bomb (rocktail)
Up to 4 other players within 2 squares of the user may be healed with a bomb, receiving health equivalent to the fish the bomb is charged with. The user will receive an extra 20% healing. Only one bomb may be deployed every 2 minutes, and only 1 bomb can heal players every 1 minute. Monsters caught in the blast will also receive healing, 5% of the monster's maximum life points.
