They made their way directly above the object. ' Dark Dealings' (1x112)Д«eaneath Thar Amphala, Vex used a Scrying Eye on the Sword and saw it submerged in muck, but got a good enough description of the object to allow her to cast Locate Object and discover that it was within 1,000 feet. The ensuing battle destroyed both Vecna and Kas, but the sword remained-though it was not recovered. Though Vecna defeated Yos, the effort left him winded, and as Yos lay dying, Kas picked that moment to attack Vecna with the blade in an attempt to usurp him. When Vecna first attempted to ascend to godhood with the Ritual of Seeding, Yos Varda attacked Vecna directly. Kas used it to terrorize Vecna's enemies for months. Vecna forged a relic blade for his new vampire lieutenant with a fraction of Kas's consciousness. Besides its thirst for blood, the main thing the Sword talks about is that 'the lich must die.' When used to attack Vecna, the Sword discussed wanting to usurp Vecna's power for itself. The Sword of Kas is singularly focused on destroying Vecna and his followers.

The Sword of Kas is a longsword, and its blade is black, beautiful, and hooked in places.
