To my understanding the engagement range applies to wounded units as well, regarding Mace Windu we have 3 cases:
not wounded Mace Windu in engagement range of not wounded enemy character - his identity ability triggers for all allies within distance 5.
not wounded Mace Windu in engagement range of a wounded enemy character - Does his identity ability trigger for all allies within distance 5?
wounded Mace Windu in engagement range of a wounded/not wounded enemy character - Does his identity ability trigger for all allies within distance 5?
Please assist, my playing group is divided regarding this matter and we would like to have your confirmation before the next tournament.
