in wow does nightfall stack with glyph of corruption?

Answer 1

They do stack, but they can both proc on the same corruption tick, essentially decreasing the value of both of them when you have them both. If they both proc off of the same tick, you only get one instant shadowbolt.

Answer 2

I'm not sure yet. In two 10 minute tests on training dummies I had nightfall proc 4 times in 5 mins and a total of 8 times in 10 minutes with just the talent.

Then I added the glyph and it procced 4 times in 5 minutes but caught up and had procced 14 times by the end of 10 minutes.

So for 10 minutes of just chain casting corruption I came up with 8 times without the glyph and 14 times with it. I'm leaning towards thinking it stacks, but I'm not sure yet.

Anyone can do this test on ptr, you don't need a Wrath of the Lich King key to try this. So lets get some more testing going, the bigger a pool of data we have the surer we can be of the truth.

PS.. I never saw it stack, but it can definetly reproc on the same corruption cast. On one Corr cast with the glyph I had it proc three times, I know cause whenever it procced I would instantly cast it.
