Lava eel

Not to be confused with the Slimy eel or Cave eel.

Lava eels require level 53 fishing and the completion of the Heroes Quest to obtain, and a cooking level of 53 to cook. When consumed, lava eels will restore 11 of a player's hitpoints. 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.

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 either Taverley Dungeon or the Wilderness Lava Maze to catch an eel.

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