ScalingMobs
by 24na7
ScalingMobs changes the stats of bosses and other mobs on a server according to how many players are nearby, so a fight grows with the group.
What it does
Health, base damage and armor of a mob are raised as the number of players near it goes up. The scaling is math-based, with the base values starting from a fixed armor of 0 and a formula built on five plus the nearby player count, which keeps the difficulty progression balanced. Bosses react more strongly than regular mobs, and mod-specific mobs react more strongly than vanilla ones.
Changes only take effect on mobs that appear inside a 100-block radius around the required number of players. A boss that appears in that area can also draw players who approach an existing boss. The mod includes preconfigured bosses from other mods, and the boss list is configurable, so server owners can define which mobs are treated as bosses. Settings are edited through a GUI that requires Cloth Config API.
ScalingMobs requires Cloth Config API, which must be installed alongside it. Server owners install it, and players can join with or without it. It is published for Forge and NeoForge, with files for 1.20.1 and 1.21.1, and the code is open source under the Apache License 2.0.
