Old School RuneScape uses the British convention for floor numbering: Ground floor, first floor, etc.
The Slayer ring (or Ring of slaying) can be used to teleport players to Slayer destinations and to contact Slayer masters.
Players can purchase Slayer rings from Slayer masters for 75 Slayer reward points. Alternatively, they can purchase the ability to craft the rings themselves for a one-time cost of 300 points. Making a ring requires level 75 Crafting. Players must bring an Enchanted gem, a Gold bar, and a Ring mould to a furnace to make the ring. Making a ring yields 15 Crafting experience, the same as an ordinary Gold ring.
Each ring has 8 charges when crafted. When they are all depleted, the ring crumbles, leaving an Enchanted gem behind. Casting High Level Alchemy on a Slayer ring produces 600 coins at full (8) charge, dropping by 6 coins per charge expended.
The Slayer ring (eternal) is an upgraded version of the Slayer ring, made with an Eternal gem instead of an Enchanted gem. It has identical functions but provides unlimited teleport charges.
The ring will teleport players to any of the locations displayed below. Each teleport consumes one charge from the ring. Similar to enchanted dragonstone jewellery, the slayer ring will allow players to teleport at up to level 30 Wilderness.
