The Dark Gift “Persistent Horror” grants: Reborn. Is Reborn with full health and enchantments. I discovered an Ur’zul Rager with that Dark Gift from Creature of Madness. I played the Rager, cast a spell and successfully triggered its Spellburst. It attacked, died, and then was Reborn but without its Spellburst being refreshed. I cast another spell but there was no effect.
I would guess that spellbursts being used is tracked as an “enchantment,” so being “Reborn with… enchantments” means the minion does not get its spellburst back.
I was so totally gonna win that game where I had to desperately discover an Ur’zul Rager, so I’d like my rank increased to at least Diamond 12
