Type: Prefix
Base price modifier: varies
Effect: When Activated, this effect provides a +N Alchemical bonus to your Spell Power for one minute.

  • For example I have an Efficacy effect that gives +12 Spell Power. Now my spells do 12% more damage compared to the base damage.

Observed effect: (tested on a randomly generated greater efficacy clicky just before Update 21)

  • The duration is longer than advertised. It lasts 3 minutes per charge.
  • Resting does not end the effect.
