Refresh my memory, please. If damage exceeds a minion in a group, it bleeds over into another minion. Example: stormtroopers A-D have 20 wounds. They take 9 damage after soak; trooper A is out, B takes 4 damage. But what if your dealing with multiple Rival level adversaries? Some of my players can do quite an impressive amount of damage. Can excess damage bleed over to the next rival?

Nope, minions are the exception to the rule that each attack can only target one enemy since they are in groups that count as one target. Besides there are other rules for damaging multiple rival level targets, such as auto fire and blast.

Ah, yes, that makes sense. Thanks.

Wounds keep going until you get to twice the threshold for Rivals and Nemesis, they cap at that.
