Dumb question but...

Like before I get to far into this game and starting adding relics and other stuff to my gear, I just want to know for right now I am playing a Sorcereres with Dual Wielding pistols. Do I want attack speed or Casting speed as far as relics?

I am using Fireblast from relic item, Firestrike as LMB and Canister Bomb as RMB. Just want to make sure I am building this right. Little weird playing a character thats title is Sorcerer but I am using guns as my weapons. I would link my build but unsure how to do that atm.


firestrike counts as attack speed.

Ok thank you
