dnd 5e – Homebrew review of “Artistic Muse” transmutation spell

This is the spell fabricate but more complicated

The spell fabricate is basically the spell you have written:

You convert raw materials into products of the same material. For example, you can fabricate a wooden bridge from a clump of trees, a rope from a patch of hemp, and clothes from flax or wool.

Choose raw materials that you can see within range. You can fabricate a Large or smaller object (contained within a 10-foot cube, or eight connected 5-foot cubes), given a sufficient quantity of raw material. If you are working with metal, stone, or another mineral substance, however, the fabricated object can be no larger than Medium (contained within a single 5-foot cube). The quality of objects made by the spell is commensurate with the quality of the raw materials.

Creatures or magic items can’t be created or transmuted by this spell. You also can’t use it to create items that ordinarily require a high degree of craftsmanship, such as jewelry, weapons, glass, or armor, unless you have proficiency with the type of artisan’s tools used to craft such objects.

Fabricate is a 4th level spell, and your spell does not require proficiency in any tools to make finely crafted objects, so I’d say your spell is actually better than fabricate. Your spell is also much more complicated, with having to keep up with successful checks, DCs, casting time, etc. Just use fabricate or one of the options below.

Maybe you’re looking for the crafting rules from Xanathar’s Guide to Everything.

This is a needlessly complicated spell that produces a product that we already have in-game mechanics for:

A character who has the time, the money, and the needed tools can use downtime to craft armor, weapons, clothing, or other kinds of nonmagical gear.

Xanathar’s Guide goes on to give some details about how this works. Anything your spell can do, I can do with the crafting rules without the possibility of failure.

Just ask your DM if you can buy some custom threads next time you’re at the market.

I’m a big fan of customizing non-mechanical aspects of your character. In one f my games, I have a bard with a rather flamboyant personality, and I have several outfits for different occasions in very loud colors. To obtain these outfits, I said to my DM, “next time we’re in town for a few days, I’d like to commission some custom tailored fine clothes.” I got my 3 sets of fine clothes tailored to my specifications for 15 gp each (the cost of fine clothes is listed in the PHB).

You don’t need a spell for this at all, and the one you have created is excessively complicated. Just buy the stuff you need or make it yourself.

Consider using existing spells.

I’ve already discussed fabricate, but if you’re looking for custom clothes, disguise self will make you look however you want for an hour:

You make yourself–including your clothing, armor, weapons, and other belongings on your person–look different until the spell ends or until you use your action to dismiss it.
