The Sinister chest is a locked chest located in the Agility Dungeon in Yanille. It is in a part of the dungeon that requires 49 Agility to access. The chest can only be unlocked with the sinister key, which is a drop from Salarin the Twisted or possible loot from a magpie impling jar. If opened, the chest will emit a toxic gas, which poisons the player starting at 62 life points, so it is advised to bring an antipoison or other method of curing or preventing poison. The ideal method is to use a prayer book to cure the poison, as there is an altar very close to the chest. However this altar will drop the player that uses it to a lower level of the dungeon, where aggressive poison spiders can be found.
