Griefcase
by Cylinder
Griefcase is a Client and server social mod for Fabric and NeoForge that gives players a set of trolling tools to use on friends.
What it does
The mod adds a collection of griefing tools aimed at prank play between players. Its items include fake ores that look like valuable blocks, a remote TNT that can be detonated from up to 250 blocks away, a cursed pickaxe, a super snowball launcher, an invisible fluid, and a non-collidable dirt block that players can walk through.
Griefcase also includes a Mr. Beast mask and several jumpscare-style effects. Because the mod is classed as a social and cursed category project, it targets server play where friends can be pranked on each other. Installation requires the mod on both the server and every player's client, since it runs client and server.
Files are published for Fabric and NeoForge across three release versions, 1.21.4, 1.21.8 and 1.21.9, with 1.0.1 as the latest build for each loader. The mod is released under All rights reserved and is not open source.
Key features
Fake ores
Blocks that resemble valuable ores but reveal themselves only when mined, so a player can be fooled while digging.
Remote TNT
TNT that a player can ignite from a distance of up to 250 blocks, without standing near the charge.
Cursed pickaxe
A pickaxe with a trick effect built in, intended to surprise whoever picks it up.
Super snowball launcher
A launcher that fires snowballs with more force than the vanilla throw, aimed at other players.
Invisible fluid and non-collidable dirt
A fluid that cannot be seen, and a dirt block that players can pass through, both useful for setting up traps.
