Does Firestorm or other channeled spells benefit from Use Rate? i remember there was a game where spells worked like that, but i don’t remember if this is the game.
Not that I know of, no. Would be interesting though, rather logical too.
The skill doesn’t have a skillgroup atm (not even the Evoker one) but it does have a very small cooldown, which means you can’t affect it by any items with use rate of Evoker skills or skillgroup, but haste bot should affect it, as it gives a generic attack speed increase and cooldown reduction.
However it might be a great way to improve this skill’s performance without a direct damage boost, and making secondary affixes more useful.
