Lord of the Night says she bring forth faith of six tribes so i have something backing it up, if you wanna assert those totems are of heroes of Natlan you get me a source saying those totems belong to heroes
Also Purifying those Totem indeed Buffed traveler (not to mavuika) but it was not Ronova buff, it was Blessings of Six tribes Buff clearly stated in travel log -
Now you get me a source saying it was Ronova Buff
Also another more obvious reason is that She quite literally soloed prime Gosoythoth
here when she had ronova buff, and Gosoythoth in Act 5 is weaker version, so if she still had Ronova Buff kindly tell me why she needed traveler's help and couldn't solo weaker gosoythoth like she soloed prime Gosoythoth? obviously she didn't had Ronova Buff by then, you are just extrapolating your headcanon
