Strands of Astral Power. Worth it?

[Ironhawk]

Yeah something does seem amiss. Even a weak spell will get lucky and defeat high MR if cast enough times. If this spell really is being cast 80 times a turn with no results then something does appear to be wrong.

Perhaps there is a mechanic to it which we are not aware? Maybe the spell literally has no effect if you are in drain dominion? Needs testing!
