I've never actually played this game, but I keep looking at your interest check. I'm thinking of putting together a psychic character. Although I am a little confused about the mechanics. If I play a psychic type character, would my attacks scale with my Intellect, or would it still be Power? And you mentioned psychic abilities being "useless" against Honkai. Does this only refer to my special psychic abilities, or would I also be unable to use my element effectively against Honkai?

In order:

Yes, psychic "power" is based on Intellect instead.

Yes, psychic abilities are historically useless on most Honkai creatures, with a few rare exceptions. Their "mindlessness" generally nullifies mental attacks and manipulation that don't originate from Honkai (and thus have an existing "in"), and only the likes of Herrschers that are built off a human template/host, have potential vulnerability. And after the sacrifice of Elysia in the First Era, precognition stopped working very well additionally, sometimes becoming entirely defunct, as she ruined the once predetermined flow of "fate". To clarify, in short, psychics are more "anti-human" than anti-Honkai when it comes to their innate abilities.

Your element, generally speaking, however, should be considered separate from your psychic abilities. Your element comes from your Artificial Stigmata, so it doesn't suffer the usual troubles against Honkai. It's Honkai-based, and it will work on them just fine. So, no worries about your element suffering against Honkai.
