Step by step
- Royal seed pod to the Grand Tree, north-west through the fence and north-east into the cavern. Avoid the multi area solo.
- Start with Protect from Magic and melee (Arclight). Count the 0s; on the 3rd pray the next style.
- When it prays Melee, swap to ranged (blowpipe or atlatl) and click again. Only body, weapon and amulet switches.
- Move 1 tile off each boulder. F-keys for prayers and inventory.
- Heal with SGS or blowpipe spec; Demonic Offering with the ashes. Pick up Zenyte shards.

Ironman tips
- 💡 Arclight (Shadow of the Storm) is among the best here (demons); Emberlight is the upgrade. Slayer helm (i) on a black demon or monkey task.
- 💡 Few switches: gloves, boots and ring aren't worth it. The Eclipse atlatl scales with melee strength and needs the fewest switches.
- 💡 Multi-hit specs (claws, DDS) get nulled if it swaps prayer between hits: use them right after it stops praying melee.
