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. If you have come to the underworld to gain favor with Grenth, then do not abandon our cause now.

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 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.


 * 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.
