Creating Custom Spells

[Bao Hadir]

So I read (or think I read) that players can craft custom spells in game. Sounds like fun.

Problems:
The thing I may or may not have imagined reading referenced wizards specifically.

Question: Is it specifically a thing for wizards? Can a sorcerer do it? What about classes with severely limited spell lists?

I specifically ask about the bard. I like my bard but I'd like him more if I could create a custom spell based off one of his other spells. In fact, I was considering a repurposed Chord of Shards, with higher damage in exchange for a single target and perhaps a performance rounds cost.

Is this possible?

Surely any spellcaster can do it. After all, the spells for any class have to have come from _somewhere_. Somewhere way back when, there has to have been a Prime Bard creating the first bard spell.

Definitely not limited to wizards, as it has guidelines for developing divine spells. The CRB however only references developing new spells in the section on wizard spells IIRC, which is what you may be recalling.
If you can cast spells, you can develop new ones.
