Immutable Form. The repository is immune to any spell or effect that would alter its form.
Magic Resistance. The repository has advantage on saving throws against spells and other magical effects.
Magic Weapons. The repository's weapon attacks are magical.
Self-Destruct. If a repository is reduced to 0 hp, it explodes, leaving behind its small, pyramidal chest cavity. Each creature within 20 feet of the repository when it explodes must make a DC 15 Dexterity saving throw, taking 14 (4d6) bludgeoning damage on a failed save, or half as much damage on a successful one.
Multiattack. The repository makes two slash attacks.
Slash. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage.
Language Lash (Recharge 5-6). The repository utters words of power, unleashing psychic energy in a 30-foot cone. Each creature in that area must make a DC 15 Intelligence saving throw. On a failure, a creature takes 14 (4d6) psychic damage and is incapacitated for 1 minute. On a success, a creature takes half the damage and isn't stunned. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
