Fell the Demon Oak in the Plains of Havoc with a hallowed axe from Oldrak while it summons waves of undead at you. Level 120, and a holy icon to be let in the first time.
Chop down the Demon Oak in the infested corner of the Plains of Havoc with a hallowed axe while it throws waves of undead at you. Level 120, a holy icon to get in the first time, and 1,000 gold for the priest.
Oldrak is in the Plains of Havoc temple at 32816, 32261, 6. Bring an ordinary axe and 1,000 gold.
He blesses as many axes as you like.
The one-tile corridor into the dead trees is at 32716, 32344, 7. It needs level 120 and, the first time, a holy icon in your backpack (it is consumed). Nobody else may be inside.
The oak at 32716, 32351, 7 has four parts – the left spiked ball, the bird, the face and the right spiked ball. Use the hallowed axe on each one ten times. Every hit costs you around 200 earth damage; the 5th and 10th hits on a part summon its guardians, the other hits sometimes four Bonebeasts:
| Part | 5th hit | 10th hit |
| Bird | Spectre, Blightwalker, Braindeath, Demon | 2 Betrayed Wraiths |
| Left ball | 2 Plaguesmiths, Blightwalker | Dark Torturer, Blightwalker |
| Right ball | Banshee, Plaguesmith, Hellhound | Grim Reaper |
| Face | Plaguesmith, 2 Hellhounds | Undead Dragon, Hand of Cursed Fate |
The very last hit summons a single Demon instead. Everything must be dead before the final blow lands. The oak then throws you out with "Tell Oldrak about your great victory".
Oldrak: demon oak – he tells you of the grave of "Yesim Adeit" south of the infested area. Use the gravestone at 32710, 32398, 7 to drop into the reward room: four chests at 32710–32716, 32393, 8, one pick.
