One problem with boss fights in Minecraft is that if the fight is prolonged, other enemies may interfere and other boss attacks may destroy your items, which can be very frustrating. This mod solves that. It prevents mobs from spawning in the world if one of your players is fighting a boss. This is also a feature that will increase TPS. Also, players will not drop items if they die only if they are fighting a boss. Outside of boss fights, items will drop as normal.
As an additional feature, this mod also gives many mod bosses the #Forge:bosses tag. The optimization will work for bosses that are given this tag. More mod bosses can be tagged using data packs.
