At 3rd level, a fey trickster’s physical form begins to shift, as she gains some of the impossible allure of the fey. At the same time, she begins able to use fey veils to assist herself and her allies in befuddling and bewitching their opponents. She can use her fey veils a number of times per day equal to 3 + her Charisma modifier.
Using the ability is a standard action (or a swift action if the fey trickster calls up a veil over herself ). If she targets another ally, the fey trickster must be able to contact the ally bodily, usually with a kiss. When she uses her fey veil, the fey trickster subtly alters the appearance and aura of her target, granting one of the powers allowed by her mesmerist level.
At 3rd level, she can grant the ally a +2 circumstance bonus on her choice of Diplomacy, Intimidate, or Handle Animal checks for 1 minute. At 6th level, she can change the ally’s form so thoroughly that the ally gains a +10 bonus on Disguise checks until the next sunrise (similar to the bonus from disguise self, but it also disguises touch and sound, and it doesn’t allow a saving throw to disbelieve).
At 10th level, the fey trickster can make the ally and her aura so attractive or repulsive for 10 minutes that the veil automatically adjusts the moods of those who see the ally and fail their saving throw, as telempathic projection. At 14th level, a fey trickster can create a veil so powerful that it fools even reality, granting the full effects of both the 6th-level fey veil and alter self to the target for 1 hour. Each of these abilities, even the 14th-level ability, is an illusion and glamer effect, though the last ability counts as a size-changing polymorph effect for the limit of only one polymorph or size-changing effect on a creature.
This ability replaces Touch Treatment
My question is regarding the bolded section above. A Will save is mentioned, but not how to calculate it. The ability is both considered a Supernatural and Spell-like ability, but it doesn't clarify which functions count as which. If the bolded section is treated as a Spell-like Ability, I'd imagine the Will save DC is calculated by the level of the spell it's imitating - Telempathic Projection (10+1+Cha). However, the ability is only imitating part of the listed spell, and expanding upon that, so it could very well be treated as a Supernatural ability (10 + [1/2 lvl] + Cha).
Seeing as this part of the ability isn't available until level 10, by which time you'll be casting 4th-level spells, and Telempathic Projection is a 1st-level spell, it feels a bit underwhelming for the DC to be only 11+Cha. Then again, this is basically an always-on, area-of-effect ability for 10 minutes, with a range of the-target-can-see-me, which is significantly more powerful than the spell's single-target, one-time-use, medium-range limitations, so maybe a lower DC was intended. On the other hand, the final product - so to speak - is a change in NPC attitudes as if you'd succeeded on a Diplomacy check, which isn't exactly game-changing, so maybe a higher DC WOULD be more appropriate.
Thoughts?
Bump
The default is 10 + [1/2 lvl] + stat for an aura. Stats can be just about anything; offhand I know about Wis, Cha and Con. For the fey trickster, I hope it's Cha but it's impossible to say 100% that's what it is.
