After taking a look at the Orc's Drops... I really don't think you can call this Exploitation.
I tired it along time ago - thinking it would be a profitable idea with my Blacksmith.
I made ALOT more by mearly walking around Nif-city killing things.
As far as I know - it was originally part of the 'Piano Keys' Quest.
I actually had access to meet the witch(Which is the end of the quest itself, I think). Unfortunately, she hates me and always throws me out of the tower.
This quest is a pre-requisite for another quest... whose name of this particular quest escapes me.
And do the monsters drop anything? o_o
They didn't drop loots, nor give any exp on my case.
