Yeah, and just for my brain clarity: the undead in the hunting forest grounds were also the burning kind, right? From what I recall they were burned soldiers.

Wei Wuxian would probably also be trying to suss out what causes personality retention versus how fast a number of the undead became creatures of only immediate instinct or being ordered by a greater power in that uh... living element (hunger, for example), compared to what he's seen now with the witches over time away from the tower, and with. Anurr. The best actor we have seen so far in the undead legions, being outside the "family" swallowing citadels.

Once he hears about the undercover illusioned undead it's even more--when is spirit retained with memory and personality, or are they all overwritten because of that one element keeping them alive and propagating... tbh feels like what he'll end up doing falls along the lines of investigating how to handle the curse of it, so I'm not expecting he's learning much anything new, just figuring out his direction myself.

Do the undead with that driving element need to be killed (right now at least) to break that "curse"?

Also to go back to the undead witches, can they be rigged with crystals or talismans that provide cooling to their, uh, skin. Cooling sensations... for the burns... cries
