Having made some changes on the back of this advice, I am now at Lvl 33 with DPS of 990. STR 424, DEX 324, INT 65.
I am doing a mix of physical, piercing, poison, cold, vitality, bleeding damage - too many types maybe...? I have a sword with cold/vit damage
My strategy is chuck in a trap or two, throw knives, then hit fast on what's left with a flash for emergencies. Seems to be working in Normal Act 4 so far.
Just checking though - for throwing knives, do all non-weapon %s apply? e.g. the cold damage and slow% from glacial rings, poison damage from Shadow Veil, +% cold/bleed/vit damage from dreadful medallion, as well as skills-based damage enhancers and "20% chance of freeze" on a frozen buckler? Not quite sure what the principle is and I couldn't find a clear explanation on other threads.
