Notes

  • Update 8.2 (2013-06-28) changed Streamline mechanics to be a linear reduction in cost.
  • It is possible to hit the hardcap of 175% Ability Efficiency thanks to Mod TT 20px Fleeting Expertise. All Ability Efficiency added beyond 175% is not represented on the UI, though may benefit channeled abilities if your duration is below 100%.
  • There is an unreleased Primed version that increases Ability Efficiency up to 55%.
