ToME: the Tales of Maj'Eyal

After changed from instant damage to a 5 turn dot, restless night become a pretty unwanted talent.
The issue is that its damage will wake up sleeping target, so level up this talent will end up wake your enemy faster.
It sort of takes insomia's job.
I think change the way it works would be good.

It doesn't trigger until the target wakes up.

But yes, it does make chain sleeping targets a bit less viable. But that's okay in my opinion.
