What happens in combat when a stunned unit has more might than its opponent?

Ruling: A stunned unit does not contribute its might to deal damage in combat, but still requires damage equal to its full might value to be killed. In both scenarios where one unit is stunned, if the non-stunned unit cannot deal enough damage to eliminate the stunned unit, the attacker is recalled.

Sequence:

• Showdown Step occurs (attacker gains Focus, triggered abilities go on chain)
• Combat Damage Step occurs if both units remain
• Starting with the attacker, each player assigns damage equal to their summed might
• Stunned units do not contribute might to damage dealt
• Units are killed if they take damage equal to or greater than their might
• If any defender remains after damage, the attacker is recalled

Nuances:

• A stunned unit with 10 might that takes 6 damage survives (still needs full 10 damage to be killed)
• A stunned unit with 10 might deals 0 damage to opponents (does not contribute might)
• The attacker is recalled in both example situations because the defender survives
