About this Mod

- Space Suit provides full cold dampening and some heat dampening when it has oxygen (must wear full suit)
- Netherite Space Suit and Jet Suit provide full temperature dampening when they have oxygen (must wear full suit)
Please disable temperature damage in the Ad Astra config. This mod intends to replace Ad Astra's temperature system with Cold Sweat.

Notice
Cold Sweat doesn't appear to be loading dimension temps from datapacks right now. For time time being, please add the following to your Cold Sweat world settings' dimension temperature offsets:
["ad_astra:glacio", -20, "C"], ["ad_astra:mars", -65, "C"], ["ad_astra:mercury", 167, "C"], ["ad_astra:moon", -173, "C"], ["ad_astra:venus", 464, "C"], ["ad_astra:earth_orbit,ad_astra:moon_orbit,ad_astra:mars_orbit,ad_astra:glacio_orbit,ad_astra:mercury_orbit,ad_astra:venus_orbit", -270, "C"]
As soon as Cold Sweat 2.3.4 is released (the fix is already implemented, just not released) this mod will work without needing an update, and you will not need to add the above to your config.
[^1]: Blood boiling is not a feature of this mod.
