Ok, maybe my grammar IS bad, I will let my log speak for itself:
N1 - test htm - your target is not royal
N2 - test Frost - your target is a Drunk
N3 - disinherit Frost - your target does not have royal blood (ability failed, 0 guards gained)
I told that fact to the court, had I gained 2 guards, I wouldn’t have pushed on you, because there wouldn’t be anything wrong.
