Ainz - Wish Limitations

“...It wasn’t about you, Albedo. The ring activated, but I found out it couldn’t grant the wish.” From Albedo’s silence, Ainz realized he needed to explain further. “...There’s only one power that the super-tier spell Wish Upon a Star can’t beat.” Before, there had been the possibility of something unique to this world being the issue, but Ainz spoke with the conviction that he now knew that wasn’t the case. He had felt it when he tried casting the spell.

“Y-you mean...a...?”

“Yes, Albedo. There’s only one thing it could be—a World Item.”

There were two hundred of them in Yggdrasil, items far stronger than even Guild Weapons and god items. Yes, for a World Item, it would probably be simple to put an undead, who should have been immune to psychic effects, under mind control.
