These are my guesses based on google searches:

Mjolnir: Melee weapon with powerful lightning magic attack. Able to be thrown and do ranged damage, returns to user afterwards. Can't be used without Megingjoro (power belt in old norse) and jarngreipr (iron grippers) equipped.

The equippment requirements would likely mess with players power builds, since Ainz has Jarmgreipr gloves (shown in volume 1) and it was a common item.

Excalibur: When drawn from scabbard, activates a light magic attack that blinds enemies. Weilder is granted HP regeneration effect, immune to bleeding status effect. Players with negative karma cannot use it.

Excalibur was supposed to be engraved with the words "take me up" and "cast me away" on it's sides, so maybe !00% chance on dropping on player's death.
