The casting time of your next Holy Light spell is reduced by 0.5 sec.
Duration: 15 seconds.
Light's Grace is a talent in the Holy tree, you will need to spend 33 points in Holy to max it.
Notes
With all 3 ranks trained, this talent will trigger for every cast of Holy Light (old), with consecutive casts maintaining a 2 second cast time, increasing the HPS of the spell significantly.
It's sometimes helpful to cast a "dummy" Holy Light right before the pull, to ensure that Light's Grace is active from the start.
