I want to make a feat with the "pick a spell" function, essentially like Fey Touched (1st-level spell from divination or enchantment school), In Tasha's Cauldron of Everything. Is it possible to do this or nah?

You sure can. Make a homebrew copy of Fey Touched or another feat similar to what you want, and you can see how it was accomplished and make the changes you'd like.

The relevant section of the Feat homebrew edit page is Spells. Here's the post about the Spells form in the Demystifying Homebrew thread for reference.

This isn’t a big report. There’s actually an entire other forum for asking about Homebrew that would be a more appropriate place to ask these questions.

Thanks for the info, i was looking for a separate place to post this but couldn't find it. thought it should be no harm if i got my answer, which i have so all g

Thanks mate, appreciate the assistance
