Voltaic Spear Farm question

Hi guys! So I made an assassin about a week ago and I've gotten used to using shadow form, and, I want to get my own voltaic spear - but I have a question Wiki couldn't answer for me:

I noticed perma's get occasionally hit by some monsters through life stealing/touch skills - is it possible to avoid this completely by only killing certain groups in the dungeon/s? And if so, which groups and in which dungeons within Slavers pls

Many thanks in advance! ^_^

you could do the Voltaic spear farm where u just run around to aggro... this doesnt require u to kill at all .... however there has been a nerf to the RoJ and CoP skills so it may now be more difficult check on pvx for the build and usage its pretty easy to learn..

Edit: in answering your questing..... yes you can avoid certain monsters but that would take learnign what monsters use these skills and you cant avoid being hit by the skill by running it just take practice and positioning... look out for necromancers they r usually the main culprits.
