Hi Rules Forum What happens when Hydra Troopers use Hydra Assault and in the subsequent attack action the target is Life Savered/ Escorted etc out of range of attack? Do they KO themselves at the end of the initial attack after Life Saver is resolved? Do they KO themselves after taking the additional action granted (that they choose as an attack action)? Do they avoid KOing themselves entirely? Thank you
