ClassBioArsenal
by BackRerd
ClassBioArsenal is a Forge equipment and adventure mod that adds player classes, monster levels and weapon and armor progression to combat.
What it does
Three core systems make up the mod: a class system that gives players distinct combat roles, a mob enhancement system that raises monster levels and attaches tags to them, and an equipment progression system for weapons and armor. Difficulty can be tuned in depth, and data packs are the way to change the gameplay values.
Both the server and every player need the mod, since it changes combat on both sides. Files are published for Forge only, across six release versions 1.20.1 – 1.20.6, with 1.3.8 for 1.20.6 as the latest file. The license is Creative Commons Attribution Share Alike 4.0, and the project is not open source.
Key features

Each player picks a class that shapes how combat plays out, giving the character a defined role.
Monster levels and tags
Mobs receive levels and tags that change their strength and behavior in fights.
Weapon and armor progression
Weapons and armor advance through tiers as the character develops, so gear gains depth over time.
Data pack difficulty
Difficulty and gameplay settings are customizable through data packs, letting server owners fine-tune the balance.
