Lava eel

Lava eels are the result of cooking a raw lava eel. They cannot be reburnt. They require level 53 fishing to catch, and a cooking level of 53 to cook, granting 30 cooking experience. When consumed, lava eels will restore 200 to 1325 life points depending on Constitution level. Lava eels may be caught using an oily fishing rod and bait in the lava rivers found in Taverley Dungeon or in the Wilderness Lava Maze.

☀If the player has unlocked the ability to fish without using bait from the Prawnbroker in the Aquarium of their house, they do not need bait to fish for lava eels. Players who wish to reside in Taverley dungeon for extensive periods of time can bring equipment (logs, tinderbox, oily fishing rod and bait) to fish and cook the lava eels to produce food for combat. This is especially true for players given Black Demons or Blue Dragons as a slayer task.

During the Heroes' Quest, guild-master Achetties will ask players to obtain a cooked lava eel to prove that they are worthy of membership to the Heroes' Guild. Players will then need to visit Gerrant in Port Sarim to learn how to make an oily fishing rod, followed by going to either Taverley Dungeon or the Wilderness Lava Maze to catch an eel.

Lava eels are also used to get the beacon keeper at Death Plateau to tend the beacon in All Fired Up (minigame).

Trivia

 * Despite living in a lava pool, you can cook the lava eel on fire. In real life, lava is much hotter than a simple campfire. This is also stated in the examine information.
 * There was previously a glitch that caused the fishing spots for lava eels to float far above the actual lava. This has been fixed.
