Just tried mist + forty + andi on a fire arrow rogue and it is havoc with my smitter.
The merc is totally safe (tele + life tap).
I am double fast in UT now
and the merc blasts non fire immunes like a train. Will try tz 96 8 player soon but I think here my hopes are probably to high.
by chance any knows the ias brakes of the rogue merc? I am currently at 40 ias and a lvl 34 fana aura, probably will sock in andi 15 ias 30 light res or 15 ias 40 ed, probably will replace andy with a 45/120 helm
