Dynamism and Darkness

The mod adds a cave biome with five mobs and eight types of trees, along with further biomes and creatures that the author plans to extend. Terrifying beasts called Bruises are found rarely within the spore forest, walking on their knuckles, with visibly muscular bodies marked by bruises. They pummel mobs with great fists and throw them across caves, and a single strike can kill a player wearing full iron armor.

Bruises have a unique ability to summon their own minions after being attacked three times. After three hits, a Bruise enters a brief brooding state marked by a red glow that swirls around its body, and any hit landed during that state calls a Hemophyter into the fight. They disorient enemies effectively but are not particularly threatening themselves, and like vexes they cannot fly through solid walls. Bruises drop Brute cells when killed, and most bipedal creatures become hostile to players near them.

The mod is built for Fabric 1.21.1 and runs on client and server, so the server and every player need it. It is released under the MIT License, and the code is not open source.
