I think if the target of the repel fails the morale check and does not attack, its morale goes down? I think I have seen this happen before. Like when a unit has fear the units surrounding that unit can get reduced morale if they fail the fear morale checks.

If the target passes the morale check and attacks it might get 1hp damage if it passes protection. As Dedas said if you keep getting 1hp damage it counts as a wound in the heavy losses requirement for another morale check.

I guess it could all add up if you had lots of repels.
