The Custom NPCs mod adds many new items and features. While it works primarily for single-player, it is multiplayer enabled. The tools are used to create new NPCs, mob spawners, and even copy them. The rest of the items are mostly used for aesthetic purposes while the weapons deal similar damage to the vanilla weapons. This mod includes extra features such as factions, roles, and jobs, dialogues, and a quest system.
