It was my transmuter groupmate casting on them. Unfortunately I'm not sure what spell. Check the "third-person view" failure & success echoes for soften, decalcify and metabolic slowing. One of them used the word "his" to refer to the spell target.I think it *might* have been the lady ranger over near the entrance to the ranger's guild there, just in case she's a different mob type from the others.
