Dialogue:
 * "These demons are relentless. I can see that they are preparing to attack me once again. My lord Grenth has granted me power over spirits, but I have no defense against the sort of bone creature they will likely use.

Walkthrough

 * As soon as you take this quest, the Slayer will spawn at the base of the mountain and hurry up the winding path. Go down to meet it and fight it. Two groups of two Keepers of Souls each will be trailing far behind it. If you cannot take the Slayer down before the keepers hostile your party, your best bet is to dispose of the keepers first.


 * Take note that if you don't see the Keepers right away you will need to stick around to finish them off. They will eventually make their way to the reaper and will kill him if not stopped by the group.


 * The fight may be long but it is not difficult. After killing the beast return to the Reaper for your reward, or hold on to it to erase Death Penalty later on.


 * The beast is relatively easy to dispatch with armor-ignoring skills. Spoil Victor comes to mind especially, due to the tremendous and unpreventable amount of damage it does.
