A waterskin carries up to four servings of water, and provides protection against the desert heat effect in the Kharidian Desert. The amount of water will be noted by the waterskins name in parenthesis e.g. “Waterskin (4)” is a waterskin that is holding the maximum amount of water.

These can be bought from Shantay, in the Shantay Pass, south of Al Kharid. Players can refill waterskins by using them with fountains, waterpumps, water-filled jugs, buckets, bowls, or water-filled vials which increase their content by 1; or using a knife/any slashing weapon with certain cacti, or with any water source. They can also be filled by using the Humidify spell from the Lunar spellbook.
