I'm currently a lvl 39 dex int enchantress. I always put 3 int and 2 dex in my attributes because I noticed that it gives better damage for both my regular attack and my spells.
My skill build right now is
6161
6000
6066
I really wanna find now which is the best attribute and skill build for pve. I don't need survivability I just want the best damage output.
