Double Damage
by 3geE
Double Damage is a data pack that doubles the damage that mobs, players and falls deal, and it doubles knockback as well.
What it does
Installing the mod means placing its data pack in the world's datapacks folder, then running the reload command after joining the world. Once loaded, damage from mobs, from other players and from falls is doubled. The author notes that the change is applied through the data pack alone, so no Java code is involved.
The server needs the data pack, while players may join without installing it. Double Damage is released under All rights reserved and is not open source. Files are published for Fabric, Forge, NeoForge and Quilt, and the data pack form is listed as a separate server platform. The latest file is 1.1 for 26.3, dated 2025-08-20, and the game versions with files run 1.21 – 26.3, across 17 release versions.
Key features
Doubled damage
Damage from mobs, players and falls is multiplied by two, so every hit a player takes hurts twice as much.
Doubled knockback
Players receive knockback twice, so a hit pushes them further than it would in vanilla survival play.
Reload after joining
The reload command is run once after joining the world so the data pack takes effect, and the author notes a death message may appear.
Coordinates on screen
The author text points to coordinates shown at the bottom of the screen while moving around, which the mod does not add itself.

Use cases
Harder survival
Server owners who want combat and falls to hit harder can add the data pack to a survival world.
Adventure maps
Map makers can use the doubled damage to raise the stakes of an adventure without writing any code.
Who it’s for: Server owners and world admins who want higher damage through a data pack, and players who can place files in a world's datapacks folder. Clients do not need the mod to join a server that runs it.
How it compares
Double Jump is a Fabric, Forge, NeoForge and Quilt mod for 1.20 – 1.21.5 that works on either side, and neither needs it. It is released under the MIT License, so it changes movement rather than damage. Slime Boots is published for 1.21.6 – 26.2 under All rights reserved, and only the server needs it while players may join without it. Every Mob Drops covers 1.20 – 26.3, and players may join without installing it, but it changes item drops, not combat numbers.
