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, or 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 material. If you’re working with metal, stone, or another mineral substance, however, the fabricated object can be no larger than Medium (contained within a 5-foot Cube). The quality of any fabricated objects is based on the quality of the raw materials.
Creatures and magic items can’t be created by this spell. You also can’t use it to create items that require a high degree of skill—such as weapons and armor—unless you have proficiency with the type of Artisan’s Tools used to craft such objects.
Why did the bit about not being able to transmute creatures or magic items with this spell get removed? Now it makes it look like you can count a living creature as raw materials for this spell.
The original version read "Creatures and magic items can't be created or transmuted by this spell." I think the italicized bit needs to be added back in.
Now that tools list specific examples of what the tools can be used to craft you might run into some edge cases for attempting to craft adventuring gear with fabricate.
This spell specifically mentions Artisan's Tools and there are three non-artisan's tools that have crafting lists in their description:
Disguise Kit can craft: Costume.
Herbalism Kit can craft: Antitoxin, Candle, Healer's Kit, Potion of Healing.
Poisoner's Kit can craft: Basic Poison.
Costumes are clothing or possibly armor so they can be covered by Weaver's tools or Leatherworker's/Smith's tools respectively.
Potion of Healing is a magic item so it's automatically disqualified.
That leaves Antitoxin, Candle, Healer's Kit, and Basic Poison as gear that, rules as written, fall between the cracks.
DM reasoning can associate an artisan's tool to cover these cracks (probably Alchemist's Supplies) or just allow proficiency with the non-artisan tool to apply for this spell as well.
So why is this not an Artificer spell anymore? Sure the two classes that get this spell now can have some nice proficiencies but they are pigeonholed into a few. Whereas one of the classes that could use this spell most doesn't get it?
I agree
Artificer hasn't been reprinted in the 2024 rules yet so it isn't listed on the 2024 spells, Artificer would still use its spell list from 2014, just with the updated spells
