I run Frenzy. I used Grief/LB combination for quite awhile, almost 2500 Trav runs before getting the second Grief. Not only did the switch save me from losing 3/10 on average corpses on Trav, but it substantially shortened the kill time. The only issue is that one run out of three, Ismael Vilehand is PI.
Berserk will cost me 3 skill points. I’d do it if it was only 1. But I also uber on the character. And Frenzy is not a build you can easily complete. Frenzy+synergies+mastery=80 points. BO is 20. Then you want BC, FI, resists, speed, and all prereqs. I’m short 7 points on taunt and 3 on sword mastery as it is, at level 92.
Ismael takes about 30 seconds to kill when PI. That is unacceptable on a 45 second speed run. I currently just FI around him, collect loot, then leave. I may try an A3 lightning merc after 2.4 hits, but will have to figure out how to keep her alive on Trav.
For now, I’m trying to figure out how efficient poison is on a character using Grief, because I have limited good lightning charms.
