OSRS Blue Moon Guide: Gear, Tornado Phase & Mechanics

Overview: Blue Moon at a Glance

Blue Moon is a full boss in the Moons of Peril group, rated 3 out of 5 in our boss index and normally fought solo.

Before you can fight Blue Moon you need Perilous Moons quest.

Tornado phase is what this fight actually asks of you, and it is the thing standing between you and blue moon armour set.

Its attack penetrates protection prayers, so praying against it does nothing.

In our index it sits in the Moons of Peril group at difficulty 3 of 5, where kill times come down to tornado phase.

Access Requirements

Blue Moon is gated behind Perilous Moons quest.

Perilous Moons quest also tends to sit alongside the other Moons of Peril gates, so it is usually cheaper to clear them together than to come back for each one. The boss requirements checklist lists them by group.

Location and How to Get There

Blue Moon is found in Neypotzli, where the three Moons of Peril are imprisoned.

Neypotzli via Varlamore, after Perilous Moons. Because the Moons share one prison, you can resupply between them — which is what makes clearing all three in one trip realistic.

Drops and What Blue Moon Is Worth

Drops worth the trip: Blue moon armour set, blue moon spear. Whether that is worth your time depends on how many kills an hour you personally get, which is a function of tornado phase rather than of your gear list.

Combat Achievements

Blue Moon has Combat Achievement tasks. With a 32 max hit the restrictions are mostly about execution rather than survival.

Task lists move with updates — read the current list in game.

Ironman Notes

Without a Grand Exchange, blue moon armour set, blue moon spear has to be earned rather than bought, and this is the fastest table it sits on.

• Ignoring that bring the right style for Blue
• Buying an upgrade before tornado phase is consistent
• Gearing for Blue Moon before finishing Perilous Moons quest
• Walking in before prayers are on
