Dungeons & Dragons 5e Element 133 Class Feature: Battle Alchemist: Fabricate Armament

You have learned how to quickly transmute raw materials into weapons. To do so, as a bonus action, you can coat any surface in chemicals to craft a weapon made out of that material. You can create any simple, martial, or personal weapon that doesn't have the ammunition or reload property.

You are proficient with this weapon and you must use the same materials normally used to create the chosen weapon (determined by your DM), or else the weapon is considered to be a improvised weapon. If you are wearing an armor made out of metal, you can convert the gauntlets of your armor into any weapon with the light property. This gauntlet weapons can't be disarmed.

You can have up to two weapons created at the same time, and creating another one makes the previous one disappear. A weapon created with this feature lasts until your next rest.
