The Sacrifice of De'lim ability doesn't destroy the target but sacrifices the target. On death abilities do not happen. Perhaps the wording needs to be changed but I would lean towards the opposite. I don't think it would be OP if the champ had the ability of the current wording. Also it doesn't refund nora for champs that aren't deployed from the rune docks. Meaning champs that are spawned (not summoned) from greenhouse, graveyard, and lich magistrate are not being refunded nora.
