jumping down the well in befallen

[Varren]

I'll soon go out to assassinate Priest Amiaz in Befallen. I'll leap down the well on the first floor of the dungeon, land safely in the pit and proceed to lay waste to whatever evil creatures assail me below. Indeed I will slay them all as I emerge from the dungeon, bringing Amiaz's magical blackened wand as a trophy to earn me esteem among my monkly mentors. I hope to earn the red sash of order.

At level 30 is this doable or a suicide mission? I've come by some decent gear and Peacebringer is my trusty staff.
