I have a question about hte mercenaries in act 3. I'm using a cold mercenary but I was wondering how you increase his attack. I mean he never uses his sword, but does his attack actually get better if you use a say poison socketed sword?
If there aren't swords which give him bonuses to his spells, you could give him a sword with bonus to resists, e.g. Silence or (not sure if he can wear it, as it's a dagger) Wizardspike - which would give him fcr as well, but I'm not sure as well if fcr works on mercs. Otherwise give him the fastest weapon available. If he decides to go into melee out of his stupidity, he would at least be through with that a little quicker.
