Cooldown Reduction (CDR) refers to the shortening of the time that a skill can be used again or chargers on a skill are available again.


Which items can have Cooldown Reductions?

Not so many as it turns out. However much of your CDR can come from skills both active and passive as well as Glyphs, Legendary Aspects and Unique items.

  • Cooldown Reduction is now capped at 75%.

How Cooldown Reductions are Calculated

Cooldown Reduction is multiplicative. For example

Your skill has a 30 second cooldown. You are wearing:

  • Helm: 6% cooldown reduction
  • Amulet: 4% cooldown reduction
  • Offhand: 7% cooldown reduction

You don't just add these percentages together.

Subtract each reduction percentage from 100% (because you want to know how much is left after the reduction):

  • Helm: 100% - 6% = 94%
  • Amulet: 100% - 4% = 96%
  • Offhand: 100% - 7% = 93%

Multiply these percentages together:

  • 0.94 × 0.96 × 0.93 = 0.839904

Subtract that result from 1 to find the total reduction:

  • 1 - 0.839904 = 0.160768 x 100 = 16%

So 16% of 30 is 4.8 meaning your skill has a new cooldown of 25.2 seconds.
