Thirst Was Reclaimed

Thirst was Reclaimed is a simple mod that adds a thirst mechanic to the game, but that fits well in modpacks (extend from TWT) by adding diverse features and compatibility with a lot of often-used mods.

This mod aimed to offer better compatibility with vanilla and other mods.

💧 Water Purity
Water can have 4 different levels of purity, depending on where it was harvested:

If you drink non-purified water, depending on the purity level, you will have a chance to get sick, or worse, poisoned. Water can be purified on a campfire or a furnace: a campfire will purify it by 1 unit, and a furnace by 2 (meaning it will go from Dirty to Acceptable, for instance).

☀ Climate & Cold Sweat
The hydration depletion speed is biome-dependent, meaning you will get thirsty more easily in hot or dry biomes, and less so in cold or wet ones. Hydration is more relevant than temperature, so building your base in wet biomes is more advisable than doing so in cold ones. This system is also compatible with Cold Sweat, and will use their more precise temperature calculations if the mod is present in the pack.

💧 Apple Skin
The mod is compatible with apple skin, showing the "quenched" overlay if the mod is present, as well as tooltips for every item that quenches your thirst.
