Re: TIE Silencer Advantage Issue
It's not a bug. Stunning is relying on potency, so it can be resisted.
When the enemy TM is over 50% then it inflicts a stun, which can be resisted. The next sentence 'Otherwise, gain Advantage' is not for the case if Stun fails but for the case the enemy TM is below 50%.
So when the enemy TM is equal or below 50%, Advantage gained. if the TM is over 50% then inflicting Stun happens.
