I completely know this is just nitpicking at a tiny thing but...
The Mesmerist's Hypnotic Stare ability says:
"The penalties from multiple mesmerists' stares don't stack, nor do they stack with penalties from witches' evil eye hexes."
Since it specifically calls out the Witch... does that mean it DOES stack with the Shaman's Evil Eye hex? RAW at least?
I'm sure RAI it shouldn't stack with the Shaman version either, but it never mentions Shaman in the text. The Shaman gains the ability to gain Witch hexes, and points out that even though some have the same name, they aren't the same hex.
"Witch Hex: The shaman selects any one hex normally available through the witch's hex class feature... The shaman cannot select a witch hex that has the same name as a shaman hex."
