It Shall Not Tick (ISNT)

This mod is no longer supported or being updated.

It was a hack to fix mob performance issues in 1.18

It Shall Not Tick (ISNT) is a performance enhancing mod that limits entity ticking to within a configurable range of players.


If the entity is within the configured range of a player the entity will tick as normal, however if it is out of range the entity will not tick and will also not be rendered by the client.

This improves the server performance by allowing the server to not tick entities that the player will not be interacting with.


The mod also integrates with FTB Chunks by allowing entities in claimed chunks to continue ticking as normal.


You can also add entities to ignore in the config, by default the following entities are ignored and an example for a modpack is included in the comments of the config.

  • minecraft:wither
  • minecraft:phantom
  • minecraft:ender_dragon
  • minecraft:elder_guardian (as of 1.0.10)
