OSRS Moons of Peril Guide: Requirements, Supplies & Rewards

Overview: The Three Moons

The Moons of Peril are three level 329 melee bosses, the Eclipse, Blue and Blood Moon, imprisoned in Neypotzli under Cam Torum in Varlamore. To fight them you need the Perilous Moons quest, and the wiki aims them at accounts with at least 75 combat. You kill them one at a time in any order, restock between fights with free food and potions made inside the dungeon, then open the Lunar Chest for your rewards.

Each Moon has 500 Hitpoints, uses a typeless three-hit melee attack that protection prayers cannot block, and is weak to one melee style. Every Moon you defeat before opening the chest gives a 1/56 roll at that Moon's armour set, so a full loop is three rolls per chest.

Requirements

The only hard requirement is the Perilous Moons quest. It needs 48 Slayer, 20 Hunter, 20 Fishing, 20 Runecraft and 10 Construction, none boostable, plus Twilight's Promise (which needs Children of the Sun). Our Perilous Moons quest guide walks through it. Finishing the quest also counts as one defeat of the Moons, so your first chest is ready when it ends.

The bare minimum to make supplies inside is 38 Herblore for moonlight potions and 30 Cooking for bream or moss lizard. The wiki notes that all three Moons can be killed with about 60 Defence in rune armour using the three stacking prayers, but calls that impractical for repeat trips, with Blood Moon the hardest at that level.

Shared Mechanics

All three fights use the same frame. Eyatlalli lights one of eight moon-phase sigils around the boss, and you stand on it while attacking. Off it you take damage every tick, starting at 1 and doubling up to 16. The lit sigil moves clockwise every two standard attacks, and when it reaches the full or new moon sigil the boss uses a special attack. The two specials alternate.

The standard attack is three hits with max hits of 4, 8 and 20, rolled against your slash defence. If one misses, the rest miss too, so defence bonuses cut your damage taken more than usual. Each hit that lands adds curse stacks (1, 2 and 5), and each Moon's curse does something different. Defence-draining specs and Death Charge have no effect, and every Moon has +500 magic and ranged defence, so this is melee content.

Other players can fight in the same room, but each boss's health is tracked per player. Nobody else's hits count toward your kill, so ironmen get full rewards.

What Each Moon Tests

Blood Moon: out-damaging her healing

The wiki calls her by far the hardest. She heals off damage she deals: 1x and 2x her first two hits, 30 to 50 on the third, 2x from blood pools and 3x from jaguar hits. In the jaguar phase you stand on the lit sigil, hit that jaguar and step one tile toward the boss as the pool forms. Stepping under her as the third hit comes out skips its heal.

Blue Moon: crush weapons and the ice

Weak to crush with -5 flat armour, so two-hit crush weapons shine. Weapon Freeze traps your weapon in one of three ice blocks; punch the blue-glowing one twice, step away from the shards, repeat. Frost Storm puts out two braziers and she heals 10 per unlit brazier five times, so relight both while dodging tornadoes. Her curse cancels your next attack at 18 stacks.

Eclipse Moon: the Clone phase

Weak to stab with 6 flat armour, so slow, heavy hits beat fast ones. In the Clone phase 15 clones attack in five waves of three; face each as it spawns to parry, and every parry hits her back with 100% accuracy, so swap to your biggest slow weapon. In Searing Rays, walk with the moon shield for one lap. Her curse makes your hits glance for 12 less.

Supplies and Inventory

You only need to bring gear and a teleport. The three camps you build during the quest have supply crates with unlimited vials of water, pestles and mortars, big fishing nets, rope and butterfly nets, and a cooking stove whose Make-cuppa option fully restores run energy. Food and potions made here are stronger than what you would bring from a bank.

• A weapon for each Moon's weakness, plus a slow, hard-hitting weapon for Eclipse's Clone phase.
• A spec weapon such as dragon claws.
• A pestle and mortar and a rope (or big fishing net) so you do not have to grab them from a crate.
• An emergency teleport. Optional, since every boss room has a quick-escape staircase.
• Optional: Book of the Dead and a rune pouch for thralls.

Everything you make is destroyed when you leave Neypotzli, and moonlight potions turn back into vials of water. If your Herblore is below 66, bring one super combat or super defence potion as well.

The Loop: Route and Kill Order

After each kill you are teleported to a camp, and which camp depends on what you have already killed. The wiki's standard route uses that to put you next to the next fight every time.

1. 1

   From the antechamber, go north-east into the Streambound Cavern, make potions and food, and kill Eclipse Moon to the south.

2. 2

   You land at the Earthbound Cavern camp.

   Restock, catch moss lizards if needed and kill Blue Moon to the east.

3. 3

   You land in the Ancient Prison.

   Kill Blood Moon in the chamber to the east.

4. 4

   You are placed back in the Ancient Prison.

   Go south to the Ancient Shrine and open the Lunar Chest, then north into the Streambound Cavern to start again.

If you die in Neypotzli your grave appears in the antechamber. The Combat Achievement Fat of the Land asks for 30 Moon kills without leaving the dungeon, which is doable because all your food and potions are made inside.

Rewards: The Lunar Chest

Rewards come from the Lunar Chest in the Ancient Shrine. You have to defeat all three Moons once to unlock it the first time; after that it opens after any single kill and resets each time you loot it.

• Each Moon defeated gives its own 1/56 roll at a piece of that Moon's set. Each piece (helm, chestplate, tassets, weapon) is 1/224.
• Duplicate protection: no repeat piece from a set until you own every piece of it.
• All three Moons killed: about a 1/19 chance of at least one unique per chest.
• No unique means standard loot instead: 1 roll for one Moon, 3 rolls for two, 6 rolls for all three.

Standard loot is atlatl darts, swamp tar, noted grimy harralander and irit, supercompost, soft clay, water orbs, wyrmling bones, maple and yew seeds, plus untradeable blessed bone shards and sun-kissed bones for Prayer. Atlatl darts can come from any Moon.

Armour pieces degrade after 45 hours of combat. A broken piece costs 1,500,000 coins to repair at Bob or Dunstan, or 757,500 at an armour stand with 99 Smithing. The three weapons never degrade. Eyatlalli will also take an undamaged Moon item as a sacrifice for roughly a 1/50 chance at another piece; any of the 12 can come back, including the one you gave her, and duplicate protection does not apply.

Completing all three sets takes 320 chests on average, and the wiki's chest table only reaches a 90% chance at all 12 pieces after 463 chests. Our Lunar Chest service runs Moons of Peril kills on your account.

Combat Achievements
