Step by step
- Fairy ring DIP. Check the eyes by the Font: only 1 player per Sire.
- Phase 1: ranged to wake him, Shadow Barrage, kill one side's vents, re-stun, the other.
- When he steps out attack him and melee on Row 1.
- Under 50% (212 HP) he walks south: Row 2 and Protect from Missiles.
- Phase 3: dump specs, run to Row 3 when teleported and finish him.
Key gear
Typical inventory
Super combat potion(4) · Super restore(4) x8 · Anglerfish x4 · Dragon dagger · Rune pouch · Dramen staff · Teleport to house (tablet)
Ironman tips
- 💡 Scorching bow with bronze arrows: vents die to 1 arrow even in full melee gear.
- 💡 Accurate weapon + Lightbearer beats draining defence with a DWH: save specs for phase 3.
