Demul, Arcane Pilferer

Requires attunement by a warlock. An attuned
warlock is proficient with this longsword. You
have resistance to force damage. Damage with this longsword is magical slashing damage. An identify
spell reveals this longsword to be a longsword of Agathys. However, this sword was bitterly cursed
by an unknown dark power to drain arcane energy around it.
