The Revenant

Walkthrough
Speak to any guard at Varrock Museum. They will say they want to know something and if you give them the knowledge they need to know they will give you a reward. He will tell you to see what caused the revenants, after that you need to go to Edgeville and talk to Oziach about any strange things lately, he will say he has seen ghosts around here, of different creatures. He tried attacking one but then it froze him and kept healing until he was forced to flee. Oziach then forged an amulet which is immune to the revenants' special attacks and prevents them from healing themselves. He will sell you the amulet for 100,000 coins, accept then go into the God Wars Dungeon.

You will see a revenant man in there if you're wearing the amulet, he will tell you that there's a curse inside the dungeon which prevents their souls from being released. Note: Take something aligned with Armadyl, Bandos, Zamorak and Saradomin to avoid being attacked. He will tell you to enter the crack on the floor, enter it and a cutscene should occur of a spirit warrior trying to defeat this beast warrior, it then dies and you see the soul being trapped, then it turns into a revenant.

Go down the hole, make sure you are wearing amulet for the fight. Attack the warrior and use Protect from Magic at all times (it will hit you hard). Keep eating food then attacking it. When it gets down to half health the revenant knight soul will attack you. Defeat it and carry on attacking the beast. Once it's dead a cutscene will occur of it dropping a spectral sigil and then suddenly a NPC player picks it up and runs away.

Then you need to search the wall for a switch and activate it, you will now be in a tomb, full of Gondavian Warriors. Keep going past them and search the crate to find a sword. Use the sword on the stone which is located in the west room, then a door shall unlock filled with level 1 unfinished souls. Kill one to get fragment, then go back to Varrock Museum. The guard will then give you a reward.
