So I had an idea for a homebrew skill feat, but I figured it wasn't complicated enough to warrent a thread to itself, so I figured that this might be a good place to put homebrew general/skill feats that are rather stand-alone and pretty basic. Essentially stuff that seems like it would fit nicely in the CRB if they had a few more pages worth of space.
For instance:
Scribe Scroll Feat 2
General, Skill
Prerequisites: Expert in Arcana, Nature, Occultism, or Religion
You can use Arcana, Nature, Occultism, or Religion instead of
Crafting to Craft Scrolls. You must be expert in the skill
corresponding to the tradition of magic of the spell you expend
when crafting the scroll. Even though scrolls have the magical
trait, you do not need the Magical Crafting feat when crafting
them in this way, though all other normal rules for crafting
scrolls apply.
I figured this was a pretty obvious skill feat, given that, while you could make the case for other consumables, such as potions or talismans, requiring Crafting to create, it seemed really strange to have that carry over to scrolls as well. Since the various magic skills seem to replace both the respective knowledge skills as well as Spellcraft, for their given traditions, this seemed like a no brainer addition.
