Extended Gamerules
by rvbsm
Extended Gamerules lets server owners set vanilla game rules more precisely, including splitting broad rules such as mob griefing into finer ones.
What it does
Vanilla game rules such as mobGriefing are broad switches that cover many behaviors at once. This Fabric mod divides several of them into narrower rules, so a server can allow one kind of block change or item drop while blocking another. The mod adds rules for entity drops, covering leashes, hanging paintings and item frames, falling blocks, and the contents of boats and minecarts. It also adds rules that keep bees and endermen from holding a grudge against players who have died.
The mod runs on the server alone, so players join without installing it. Fabric API is required and must be present on the server next to Extended Gamerules. Builds exist for 1.21.11 only, with 1.0.0 as the latest file, published on 2026-02-14 under the MIT License, and the code is open source with public source and issue tracker links.
Key features
Finer vanilla game rules
Several existing game rules are tuned to cover narrower cases, so a server can set them with more control.
Split mob griefing rules
The broad mob griefing rule is divided into separate rules, for example to stop creepers from breaking blocks without disabling other mob effects.
Entity drop rules
Rules decide whether leashes, hanging paintings and item frames, falling blocks, and vehicle contents drop when the entity is removed.
Forgiveness after death
Separate rules let bees and endermen stop targeting a player after that player has died, instead of holding a grudge.

Use cases
Tuning a creeper-friendly server
A server owner can keep creeper explosions and still stop them from destroying blocks, using the split mob griefing rules.
Adjusting item loss
Entity drop rules let a server keep boat and minecart contents or hanging decorations from dropping on removal.
Who it’s for: Server owners who want to adjust individual vanilla game rules on a Fabric server running 1.21.11.
How it compares
NoCreeperDamage is a Fabric, server-side only mod under the ISC License, and it targets creeper damage alone. Detailed mobGriefing is also Fabric and server-side only, released under the MIT License, but its files cover 1.21 – 1.21.11. Practical Gamerules is a client and server mod for 1.21.11 under All rights reserved, so it must be installed on both sides.
