Simple, fast boss (60-100 kills/h). A single typeless attack (max 8, every 2 ticks) that ignores prayers: mitigate it with magic defence, walking under him or Redemption.

⚠→🚫

Typeless attack

Max 8, very accurate, every 1.2 s, 8-tile range. Prayers do not block it; magic defence helps.

⚠→🚫

Smoke

Facemask, Gas mask or Slayer helm mandatory or the smoke damages you and drains stats.

⚠→🚫

Walk-under

After each hit walk under him: he attacks once per hit of yours (50-60% less damage).

⚠→🚫

Redemption

At 49+ Prayer, under 10% HP it heals 25% of your Prayer level. Stay at 9+ HP, drink and reactivate. Zamorak brews are the cheap option.

Your magic reaches 9 tiles, he reaches 8: freeze him and step out of range (staff on longrange). Not with Eye of Ayak.

1. Fairy ring BKP, north-east to the Smoke Devil Dungeon, north-west through the crevice.
2. Slayer helm or facemask and armour with good magic defence.
3. Melee with Piety; hit and walk under (click the west door for the 1:1 rhythm).
4. Respawns in 9 s: chain kills. Death Charge for more specs.

• 💡 Without a scythe the Ring of suffering (ri) recoil out-damages a Berserker ring. An imbued heart raises your magic defence.
• 💡 With Trident/Sang and Blood Barrage you out-heal his damage, but it is 2-3x slower than Shadow.
