the Magnificent Fire-Breathing Sword-Swallowing Maw!

The mod gives players two linked abilities. Holding something fiery in the hand, such as a torch, campfire, blaze rod or blaze powder, lets the player breathe fire by pressing the Breathe key, which is bound to a default key. Fire breath applies potion effects that carry fire and can set hit entities alight, and it works without any ignition source once the effect is active.

Sword swallowing is the second feature. A player can swallow an iron sword, which reverses a draconic transformation and returns the player to their earlier form. Swords become edible through chomped versions that keep the same name, enchantments and everything else, and the conversions are driven by recipes and tags that the mod adds. Vials become a snack once they are used up.

The mod runs on the client and on the server, so the server and every player need it. It is published for Fabric only, for Minecraft 1.21, with the latest file 1.4.7 for 1.21 dated 2024-07-08. It depends on Fabric API. The source code is public and the code is under the MIT License, so the mod is open source.
