You summon a +3/+3 black longsword to your hand that does 1d10 slashing on a hit. when an aberration is nearby (within 800 ft.) the blade activates and gets enveloped by a purple,blackish energy. when activated in this way the blade does 2d10 extra necrotic damage and it gains the reach property. (10 ft.) Once per summon, you can try to banish all aberrations within 60 ft of you. (see the banish spell) This counts as one attack.

Duration: 3 attacks or up to 1 minute.
