First, you need to go to the Plains of Havoc and search for "the infested area" (here). It is surrounded by a lot of Dead Trees, east of Dark Cathedral and north of the vampire's house. There you will find a 1 sqm corridor that leads into the center. (There is no Gate Of Expertise but you do need to be level 120 or above to be eligible for entry) Surrounding the infested area there are 5 squares that cause the Demon Oak to yell. However, once inside the infested area you must then leave and speak with Oldrak who will then make you a Hallowed Axe after bringing him a normal axe and 1,000 gp.

There you will find a 1 sqm corridor that leads into the center. (There is no Gate Of Expertise but you do need to be level 120 or above to be eligible for entry) Surrounding the infested area there are 5 squares that cause the Demon Oak to yell. However, once inside the infested area you must then leave and speak with Oldrak who will then make you a Hallowed Axe after bringing him a normal axe and 1,000 gp. Once you have acquired the Hallowed Axe return to the Demon Oak and start to attack its 4 most vulnerable points: 1: The left spiked ball 2: The bird 3: The face of the tree 4: The right spiked ball Attacking these four points will anger the Demon Oak and cause him to summon monsters. Once attacking the four points you will have to keep attacking that same area until it is "Dead" or "puffs smoke". Depending on which order you choose to do the four points the demon oak summons different monsters. Here's the pattern: Left spiked ball: 5th hit = 3x braindeaths + 1x bonebeast 10th hit = 2x betrayed wraiths Bird: 5th hit = 3x liches 10th hit = 1x dark torturer + 1x blightwalker Right spiked ball: 5th hit = 3x banshees 10th hit = 1x grim reaper The face of the tree: 5th hit = 2x giant spider + 1x lich 10th hit = 1x undead dragon + 1x hand of cursed fate For hits 1-4 and 6-9 it's random if the demon oak summons nothing or 4x bonebeasts. The 10th hit on the last of the four points is always 1x demon instead of what should've spawned. I.e. if you do the face last you get demon instead of undead dragon + hand of cursed fate, and if you do the left spiked ball last you get demon instead of 2x betrayed wraith and so on. Once the tree is 100% dead, you may leave and speak to Oldrak again to tell him you have defeated the Demon Oak. Once this is done, go to a grave stone which is located south of the infected area with the name of "Yesim Adeit" (Which can be read as "Yes I made it"). "Use" the grave stone to enter the rewards room and choose your reward. Image:Gravestonedemonoak.jpg|Grave Stone Image:Demon Oak quest Reward Room.png|Reward Room
