it was the eyes of pallas that made her immune (mostly) to tp but the 'upgrade' wasn't consistent all the time. she has some tp resist feats both before and after, but the eyes are cited as the reason she was immune to max lord's attempts at control for one thing and she has a few other feats along that line as well. really though, it generally takes an uber tp to get through to her. at least it did. tbh i can't see her going backwards in this area given the feats she's wracked up. she must have gone up against some tp's since the reboot, i just can't recall any offhand.
