I'd like to suggest some compatibility features with EnvironmentZ. EnvironmentZ has weather effects in the overworld and nether, and requires proper gear for dealing with temperature extremes. Unfortunately origin choice doesn't affect how temperature works in EnvironmentZ, the yeti freezes to death in the snow and blazeborn overheats in hot enviroments. It would be awesome if origin choice also had an impact with EnvironmentZ. I think characters should be immune to their preferred weather and extra susceptible to the other. I believe this would create a more enjoyable experience in modpacks that have both of these great mods. I have also made this suggestion on the EnvironmentZ page

Closed because I just learned they have tools available to implement this already, through the action on callback feature, origins:action_on_callback and origins:execute_command. The EnvironmentZ mod then has commands to change climate affectation
