Passive Mobs
by Sedushi
Passive Mobs lets each player set how aggressive mobs are toward them, so players on one NeoForge server can choose different difficulty levels.
What it does
Players choose their own aggression level for mobs, and mobs behave normally toward a player who has chosen the default setting. A player who has chosen a passive setting is ignored by mobs until that player attacks one, and mobs cannot be damaged by a player who has chosen to ignore them. Because the setting is per player, one server can host a hard difficulty for experienced players and a gentler one for less skilled friends.
Starvation and other non-mob damage remain governed by the server's difficulty setting; the mod only alters how individual mobs respond to each player. The mod is server-side only and is published for NeoForge 1.21.10, with the 1.0.3 build dated 2025-12-22. It is released under the MIT License and is open source, and its source code and issue tracker are public.
Key features
Per-player aggression
Each player sets an aggression level for mobs, independent of the levels other players on the same server have chosen.
Passive until attacked
Mobs ignore a player on a passive setting until that player attacks one of them.
Ignored mobs take no damage
A player who has chosen to ignore mobs cannot damage them, which keeps those encounters non-combat.
Mixed difficulty on one server
Players of different skill can share a server, each playing at the difficulty they choose.
