I’ve noticed a weird behaviour with Arcane Ascendance when used together with Meteor; I’m not entirely sure if the spell damage bonus is applied when you cast the meteor, but rather only when the impact happens. This means that you would have to cast meteors first and then activate AA before the first one hits the ground to actually get the extra damage.
I made an album with some GIFs to demonstrate this.

It would make more sense if you get the bonus damage the moment you cast meteor instead of when it impacts, because meteor has a massive delay from when you cast it and when the impact happens.
Of course, I’m not entirely sure if this is how it behaves because it’s incredibly hard to test it on the dummy, but I figured I’d make a bug report just in case it doesn’t work like it should, and let you guys investigate it.
