Rampant

Rampant alters the behavior and stats of hostile mobs. Affected mobs move faster, lunge at the player, and can cover ground quickly when a target gets close. Some hostile mobs also fire twice in quick succession, and projectiles travel at a slightly higher speed. Slimes split into between 2 and 6 smaller slimes, and a small share of spawns, about 1 in 20, appear charged.

The mod also changes how creepers and similar mobs react. An explosive mob can detect a player standing behind a block and move toward them, so cover is less reliable. Rampant is meant to work alongside other mods that modify base game hostile mobs. Because it is built for BTA Babric, it is only available for b1.7.3 and is not a mod for later Java Edition versions.

Rampant is published under the CC0 1.0 Universal license, which places the work in the public domain, so the project is not open source. Snapshot builds are published, and the environment is client and server, so the server and every player need the mod.
