Need is... in Locked Tomb terms she's kind of a bootleg Lyctor in that she is a fantastic fighter and pretty good thalergenic specialist with a side of neutralizing other peoples' theorums, with a strong presence in the River, and got to this point by living as a cav for a couple decades before embracing her inherent necro potential, then in her old age sacrificing herself and spending around four thousand years as a revanant in a sword. (the metaphor is not perfect)

Usually in the physical world she's just a sword and has to work through living people, but here she is as if in the spirit world - simulating the body she had when she died, seventy-ish and without the ability of youth but not an invalid yet. So. The odds favor Need winning a spar, but Cam might be able to manage an upset even with Pal's body!
