Make it a talent point.
As base-line, plane-jane Holy Nova. Does damage. Reveals stealthies, you can spam it, it’s a bit weak, ect. <-A nice little utility filler.
Give it Three (3) talent point choices below it.
Choice 1
Shining Force.
4% of base mana
Instant.
40 yard range.
120 sec cooldown.
“Become immune to snaring and slow affects for 3 seconds,
creating a burst of light around a friendly target,
knocking away ALL(*1) nearby enemies and stealing 50% movement speed (for maximum of 150%) from the most mobile targets.
(*1)HAS NO AFFECT ON STEALTHED TARGETS”
This allows it to be cast on friendly targets as well, but the speed stealing only goes to the priest, and the slowing will make a monk or two think twice about spamming
all that green crap in my face all the time, and if it hits the pets of a hunter/lock/dk/whatever else sending all of their pets to the priest, they all get slowed.
Choice 2
Unholy Nova. Replaces Dispersion.
2% of base mana
Instant.
20 yard range.
120 sec cooldown.
“Disperse into pure shadow energy, reducing all damage taken by 80% for 6 sec. but you are unable to attack or move.
Canceling this spell early will root all targets within 20 yards, with a 50% chance of placing a (DOT) or (fear) when the root ends,
and a 50% chance of placing a root and (x3 mind blast damage) when the root ends.”
It’s a bomb.
Choice 3
Blizzard’s choice.
Don’t prune those fade talents, my dude.
Everybody loves fade in the talent tree.
Edited it to make Shining Force more fair.
