Try not to ask questions that can be answered by reading the tooltip.
I am wondering if arcane focus applies the 3% hit to all spells or just arcane. I'm currently sitting at just over 17% hit from gear alone. I thought I previously found a post on these forums saying that it only applies to arcane spells, I can't seem to find that post anymore. I made it a point to get my gear +hit to the cap because I don't generally run with a SP or Boomkin. Any help is appreciated.
