OSRS Moons of Peril Lunar Chest Simulator
Welcome to the most comprehensive Old School RuneScape Moons of Peril Lunar Chest simulator available online. This interactive tool allows you to virtually open Lunar Chests after defeating the Eclipse Moon, Blood Moon, and Blue Moon, using authentic drop rates and mechanics directly from the game.
What is a Lunar Chest?
In Old School RuneScape, after defeating one or more of the Moons of Peril in Neypotzli, you can claim a Lunar Chest containing random rewards. The chest's contents depend on how many moons you defeated, with more moons providing more rolls on the loot table and chances for unique moon equipment.

Lunar Chest Mechanics
- •Moon-Specific Rolls: Each moon defeated gives a 1/56 chance at any piece from their complete equipment set, independent of other moons
- •Duplicate Protection: You won't receive duplicate pieces from the same moon until you've collected all pieces from that moon's set
- •Standard Loot: If no unique drops, you get rolls on the standard loot table (1/2/6 rolls for 1/2/3 moons defeated)
- •No Overlap: Getting a unique prevents standard loot from dropping in that chest
- •Set Completion: Once you have all pieces from a moon's set, you can receive duplicates of any piece from that moon
