The Death Knight that were summoned in Vol. 1 is permanent because Ainz using corpse. The temporary one you said he summoned it using an item (sword). So the condition for summon a permanent monster is by using corpse.Dark Young need more corpses to summon probaly because its level is much higher than the DK.

If you heard about the side story about the Death Knight. It's the same one he summon in Vol. 1.
