In a 2v2, Hyaenid Executioner used Death Sentence on a Skywing Patrol with many negative conditions. All banners except for the banner for the owner of the Executioner were out. Death Sentence was used, ap was expended, and Skywing Patrol lost no hp. edit: LOL WRONG FORUM.
If he's Defiled, no statuses (negative/positive) can be cleansed, thus no damage. Was he Defiled at the time?
I don't believe so, it was the Hyaenid public decks. The only other champions hit him were Instigators, Spearman, Executioner, and Pack Leader.
