Ravenous Maw

About

⚠ WARNING: THIS MOD REQUIRES PATCHOULI & NEOFORGE TO WORK.

Ravenous Maw is a mod that allows you to tame a living monster that gradually mutates over time. If you can earn its obedience, it becomes a powerful omni-tool that can be shaped and enhanced through Feasts and Mutagens using the Mutation Matrix.

Your Maw is alive—and hungry. You can regenerate (repair) it by feeding it Feasts through any crafting apparatus, so don’t forget to keep the beast well-fed. To advance your Maw through its stages, you must defeat the Wither, the Ender Dragon and the Warden, in that order. Every player who wounded the boss shares the credit, and their Maws ascend with it.

Features

• Multiple questionable food options called Feasts (they’re for the Maw, not for you)
• Four Ravenous Maw variants, each with their own unique stage
• 14 Mutations, each with unique abilities and instabilities
• 5 Assimilations: traits the Maw grants _you_, earned through deeds
• A block called the Mutation Matrix for applying Mutations
• An in-game guidebook: Mutation Codex
• A crafting ingredient called Contaminated Core
• Optional JEI support

Mutations

Each Mutation alters the Maw in dramatic and often dangerous ways. Higher stages unlock more of them.

Latent

• Tectonic Bite: A classic hammer-style upgrade. Mining area increases with Maw Stage (up to 9×9). Sneak to break a single block. It can be disabled.
• Electric Mending: The Maw feeds on Forge Energy (FE) to repair itself, and the reserve grows with each Stage. Every blow costs current, and a Maw left dry strikes feebly. Paired with Undying Flesh, hits are free and arc lightning to up to three nearby mobs.

Advanced

• Combustive Enzyme: Hits mark enemies as _Combustive_, causing them to take increased damage for a short duration. Fire Aspect hits explode after a short fuse.
• Mental Supremacy: The Maw’s gaze intimidates wild creatures into submission, taming them.
• Iris Out: Launches homing or standard projectiles. Targets the cursor and ignores unseen mobs (including those behind you). It can be disabled.

Noble

• Undying Flesh: The Maw becomes completely unbreakable.
• Symbiotic Aid: Purges harmful effects from you while held, keeps the Maw in your inventory on death, and adds Armor Toughness.
• Tendril Lash: Extends interaction and reach distance while the Maw is held.
• Insatiable Voracity: The Maw grows stronger with every kill, up to a ceiling that rises with each Stage.

Excelsior

• Resonant Rending: Enables the Maw to deal damage based on a percentage of an enemy’s maximum health.
• Arcane Hypertrophy: Doubles the potency of Fortune, Looting and Sharpness.
• Indomitable Will: Removes mining speed penalties while airborne or underwater.
• Perpetual Motion: Each hit drains life, healing you, quickening your stride and sating your hunger.
• Adaptive Shift: A flexible Mutation that allows:
• Switching between Silk Touch and Fortune
• Sacrificing loot to temporarily increase damage
• Fine-tuning mining speed (up to the maximum limit)

Assimilations

The Maw doesn’t only change itself. Perform the right deeds while carrying a Maw of the right Stage (or higher), and it will begin to change _you_. Each Assimilation is tied to a Stage and earned, not crafted:

• Gilded Pheromones (Latent): Spend time in the Nether. Piglins and hoglins ignore you, and bartering pays better.
• Nictitating Membrane (Advanced): Spend time in the End. Endermen ignore your gaze.
• Aquanaut Coalescence (Advanced): Slay an Elder Guardian. You breathe underwater and swim faster.
• Oxytocinergic Esca (Noble): Win a Bad Omen V raid. Villagers give you discounts that stack, and send gifts.
• Eldritch Antenna (Excelsior): Earn the other four and own a Maw with all 14 Mutations. Mobs no longer start fights with you (bosses, Elder Guardians and raiders excepted). It can be toggled in the config screen.

Each one has its own advancement, ending in Fully Assimilated.

Development

Ravenous Maw is my first Minecraft mod and is completely open-source. You’re welcome to check out the source code here—though I can’t promise it won’t hurt your eyes.

Due to hardware limitations (yes, I’m running on a potato), the mod hasn’t been tested as extensively as I’d like. Please expect the occasional bug. If you encounter any issues, feel free to report them on the GitHub repository. Feedback of any kind is greatly appreciated.

This mod is inspired by Tinkers’ Construct and JustDireThings.

Future Goals

• Adding a Feast Smoker block for a more immersive Feast-crafting experience
• A wiki page to provide detailed documentation, progression guides, and mutation breakdowns
