Got a little bit of time to play today, so have some updates!
Izual wasn't difficult, just slow. Set him up for my merc to tank him while I spammed Firestorm. Again, Fissure sucks ass against stationary targets/bosses.
Well thank you Hephasto! It was a 4% Manald.
Act 4 is pretty slow going, lots of monsters with good fire resist.
Pretty happy about my forge drops
