Corvus didn´t power drain with SP2

RaveNN

I was in Sinister Labs, enemy ultron had: Power Gain 200%, Power Gain 200% for both champions and Force of Will.
When I SP2´d him he was at full power and didn´t lose anything

You need to have Glaive charges for that, did you have Glaive charges?

If it was classic ultron his armor buffs reduce offensive ability accuracy per charge and can fail the power drain, even the unblockable. One scenario could be the first two hits causing ultron to gain armor buffs and failing the power drain from the third hit.
