TNT Damage Booster

by Stepan1411

Servers that want heavier TNT can raise its blast damage with TNT Damage Booster, a Fabric, Forge, NeoForge and Quilt mod that sets a damage multiplier from a command.

FabricForgeNeoForgeQuiltServer required, client optionalAll rights reserved1.20.1 – 26.2

What it does

Stepan1411 built the mod to increase the damage TNT deals to players, mobs and blocks in the explosion radius. The strength is set by a multiplier that can be changed with a simple command while the server runs, so servers can move from standard damage to double or five times the default without a restart. Damage drops off with distance from the blast, as it does for vanilla TNT, and armor defense and the Explosion Protection enchantment are applied correctly.

Server owners who want the change to be a data-driven setting can use the datapack build instead. It lets the TNT damage value be altered in real time, and the files can be deleted from the datapacks folder when the change is no longer wanted. The mod is described as lightweight, with minimal performance impact. Orbital Strike Cannon is an optional dependency and is not needed to run the booster.

Only the server needs the mod: it is server required and client optional, so players can join without installing it. Files exist for 1.21.4 as the latest build, and the mod is published for Fabric, Forge, NeoForge and Quilt across 22 release versions, 1.20.1 – 26.2, under All rights reserved. The code is not open source.

Key features

  1. Adjustable damage multiplier

    A command changes the TNT damage multiplier, with presets for standard, double, five times and half damage.

  2. Distance-based falloff

    Damage decreases with distance from the explosion, following how vanilla TNT behaves.

  3. Armor and enchantment handling

    Armor defense and the Explosion Protection enchantment are applied to the boosted damage.

  4. Datapack version

    A datapack build lets the TNT damage value be changed in real time and removed by deleting its files.
