Sulphur Lizards are creatures found in the middle level of the Karuulm Slayer Dungeon in Mount Karuulm, requiring level 44 Slayer to kill. As they are only found within the volcano, players must protect themselves from the extreme heat of the dungeon floor by wearing either boots of stone, boots of brimstone, or granite boots, which don't require a Slayer level to wear. However, players who have completed the elite Kourend & Kebos Diary can wear any type of footwear without being rapidly burned.
Players can kill these as an alternative to Desert Lizards, provided they have the higher Slayer level. However, sulphur lizards do not require ice coolers to finish off.
Sulphur Lizards access the gem drop table fairly frequently, making it a good low-level monster to kill for ironmen players seeking a shield left half or dragon spear.
Drop rates estimated based on 23,200 kills from the Old School RuneScape Wiki drop log project, unless otherwise cited.
