Block Mimic

Break a block. It might break you back.

Any block you mine can wake up and come after you. The harder and rarer the block, the deadlier the thing that comes out of it — a dirt mimic is a nuisance, an obsidian mimic hits straight through your armour, and a netherite mimic is a full boss fight.

A mimic is the block you broke

It wears the block's texture. It keeps the block's drops. And it fights in a style that suits what it is made of:

Touching one does what the block would do. Magma sets you on fire. Ice slows you. Cactus and dripstone cut through armour. Slime bounces you. Honey glues you in place. Soul sand drags you down.

Mining drops nothing

A mimic carries the block's loot and its experience until you put it down. Kill it and you get everything back, plus food made of whatever it was made of.

Twenty-seven food families, each with its own effect:

• Copper food — every ore within 16 blocks glows through solid rock, each in its own colour, for 30 seconds.
• Gold food — night vision that stacks, up to fifteen minutes.
• Diamond food — 5 hearts of absorption and 3 minutes of Luck.
• Emerald food — regeneration and Hero of the Village.
• Sculk food — invisibility. Prismarine — water breathing and Dolphin's Grace. End stone — slow falling and jump boost.

Every family has its own texture, and they stack separately in your inventory.

The netherite boss

Break ancient debris or a netherite block and the fight changes. Darkness falls, the block swells to two and a half times its size, lightning comes down for ten seconds — and then it starts reading the room.

• Hiding behind cover? It plants itself and throws four to seven bursting fireballs through the wall.
• Keeping your distance? It crouches, then swoops — one diagonal rush to five blocks above your head — hangs there just long enough for you to run, and drives straight down. The landing throws a ring of TNT.
• Standing too close? It grows again and spins, accelerating the whole time, chewing sideways through the terrain. Touching it is close to fatal and throws you seven blocks.

Below a third health it enrages: bigger, faster, harder, and the storm comes back.

The mimic lure

Mimics are a chance on every break, so you can go a long while without meeting one. The mimic lure fixes that. Craft it from mimic food and a glow ink sac, right-click it, and the next twelve blocks you break all wake up.

A charge is spent only when a mimic actually appears, so mining water, bedrock or a chest costs you nothing — twelve means twelve. The recipe shows up in your recipe book the first time you pick up mimic food.

Two modes

Every world picks one on first join, and you can change it any time with /blockmimic mode:

• Default — mimics show up as often as the block is hard and rare.
• Streamer — every block that can become a mimic always does. No per-player or per-chunk limit.

Built for servers

• Hard caps on living mimics per player, per chunk, per tick and per server. The server-wide cap binds every mode, streamer included.
• Area-protection mods get to refuse a break first; mining machines and fake players never trigger a spawn.
• The boss only chews terrain when mobGriefing and the mod's own bossBreaksBlocks are both on — turn the latter off and every pattern still works, your base just survives.
• Only operators, or the singleplayer and LAN host, can change the world's mode.

Configure anything

Everything lives in config/blockmimic.json — spawn chance, health and attack curves, caps, boss behaviour, food values.

And every rule about which blocks do what is a block tag, so a datapack can change any of it without touching the mod: which blocks can spawn, which are blacklisted, how rare each one is, which combat style it uses, what it does when it hits you, and what food it leaves. Per-block overrides go in data/<namespace>/blockmimic/override/<name>.json and reload with /reload.

Requirements

• Minecraft 26.3
• Architectury API — both loaders
• Fabric API — Fabric only

Fabric and NeoForge get exactly the same features, built from one shared codebase.
