What happens when an attacker attacks a stunned unit with more power than the attacker's power?

Ruling: If the attacker cannot kill the stunned defender and the attacker is still alive after combat, the attacker returns to base. The defender remains in place.

Nuances:

• This interaction is similar to how Kayn works: if any defending unit remains after combat, the attacker bounces to base
• The defender does not move because they were not killed
