This was totally possible before, but the new Terror anointments are wild and you should totally farm them.
Like you exemplified Zane is far from weak XD. I think a ton if people may have been expecting Jack 2.0 from TPS where you could literally nod off during combat and still kill everything. Zanes Holo Twin and Barrier are two of my favorite action skill in the series.
If I had full rocket launcher ammo at the beginning of the fight I could’ve killed him even faster.
I’ve farmed him about 100 times now since last night looking for a Freeman with +100% splash damage on action skill end.
EDIT: uploaded a faster kill for the interwebs
