How do i beat shertul priest with gunslinger ?

[Mckertis]

I mean seriously. I got him one time with a butcher, but gunslinger...
Playing on nightmare, basically the whole campaign is smooth sailing with net projector and later net + vital shot. But there is very little i can do to that boss. He ignores the net and stuns. He has endless bone shield that cannot be disabled (even though static shot claims to be able to, never seen that work) and takes ages to get through. Gunslinger just doesnt have any real disablers or multi-hit attacks. And when i do get through his shield, i hit him with vital shot for 1000 - he heals 22000. Come on now, what ? I just quit. What's even the point anymore.

Have to agree. My own Nightmare EoR gunslinger run was smooth as butter up until the final boss, when I just could not win for the reasons you mentioned. I think that antimagic might be necessary if I ever care to try it again.
