These registries load when the world opens. Reopen singleplayer or restart the server after editing them. The [datapack catalog](https://movblock.mov/ntm-next/wiki/catalog.md) lists each registry's server and client use.

> ## Tags
>
> `#hbm:radiation_immune` lists entity types that accumulate no radiation and suffer no radiation sickness. Changes apply on `/reload`. The shipped tag contains Quackos The Elder One (`hbm:entity_elder_one`) but not the Duck (`hbm:entity_fucc_a_ducc`), so the shipped `hbm:duck` [irradiation transformation](https://movblock.mov/ntm-next/wiki/hazards-and-radiation/irradiation-transformations.md) turns a Duck at 200 RAD into Quackos.
