Salty Mod is one of the most for built for aesthetic purposes, some features still make it a worth while addition aside from introducing additional new minerals and blocks. Salt crystals will now grow from caves and other locations once you use this mod.
While the salt in powdered form can be used in cooking to provide an additional boost than the usual hunger satiate effects, you still have to extract them from salty mod crystals. This is perfect for longer journeys and exploration as well as neutralizing the ‘rotten flesh’ effect/status on food so you can consume them again and avoid waste!
You’ll also find salt lakes around the world and underneath them you’ll find blocks of mineral mud. You can create mud mask armor with this, which isn’t very durable but it will provide some health restoration over time. Be careful near water though as it will dissolve over time.
