"Force 5, usable once per skirmish, replaces turn or when this character would be defeated: This character has 10 Hit Points, is considered activated and cannot attack or be damaged. When an enemy in Luke's line of sight targets, allies of Luke are not legal targets and do not count as the nearest enemy or adjacent. The enemy can target Luke, ignoring cover. At the end of the round, this character is defeated. This Force power cannot be cancelled."
I am little confused

. This seems contradictory; it states that Luke "cannot attack or be damaged", but then it states "The enemy can target Luke, ignoring cover."
Can someone please clarify this?
