Yorick can get two Maidens after dying in Mordekaiser's Death Realm
Since an undocumented V25.09 change made the Maiden follow Yorick into Mordekaiser's Death Realm (recorded as "Undocumented" on the League of Legends Wiki), players report that if Yorick dies there the Maiden can survive while his ultimate goes on cooldown, so he can summon a second Maiden later. The interaction was never described in the patch notes, and no patch note fixes it.
