OSRS Dagannoth Prime Guide: Best Gear, Strategy & Drops

Overview: Dagannoth Prime at a Glance

Dagannoth Prime is a full boss in the standalone boss group, rated 3 out of 5 in our boss index and normally fought solo.

Before you can fight Dagannoth Prime you need Horror from the Deep.

Prime magic positioning is what this fight actually asks of you, and it is the thing standing between you and seers ring.

Its own attack is magic, so Protect from Magic is the prayer it asks for.

In our index it sits in the standalone boss group at difficulty 3 of 5, where kill times come down to Prime magic positioning.

Access Requirements

Dagannoth Prime is gated behind Horror from the Deep.

Horror from the Deep also tends to sit alongside the other standalone boss 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

Dagannoth Prime is found in the depths of the Waterbirth Island Dungeon, alongside Rex and Supreme.

Waterbirth Island from Rellekka, then down through the dungeon. Prime is the Magic-based King, so the walk in is also when you decide whether you are camping Prime alone or rotating all three.

Drops worth the trip: Seers ring, Dagannoth Prime pet. Whether that is worth your time depends on how many kills an hour you personally get, which is a function of Prime magic positioning rather than of your gear list.
