I just fired twice wilbur’s effect, twice. And it did nothing on ennemies. In this picture i fired wilbur’s special for a second time. No def -, no spirit link. This sas on a war battle. Btw there where 2 heroes alive when he fired his special for first time. No spirit link.
I have no dispellers in this battle, enemy had no cleanser.
similar bug with heroes that apply def - : Tiburtus for example.
