Barrel of Everthirst

Wondorous item , rare (requires attunement and constitution score of 15 or more)

The Barrel of Everthirst is a small , 2ft wide and 1.5ft high barrel that can hold up to 35 gallons of liquid inside . It uses basic transmutation and moderately advanced conjuration concepts to allow it's attuned user to magically manipulate it's contents .

While attuned to the barrel , it feels light to you even when filled . It instantly generates liquid so that it always contains at least 5 gallons in it . You can change the designated liquid at will , choosing water or the last digestible non poisonous liquid that was poured into it . Liquids that already carry magical properties are not affected by this barrel’s enchantment .

If you are within 100 feet of the barrel , you know the Shape Water cantrip and can target liquid that was generated by the barrel ; if you did not know it before hand , the liquid generated by the barrel is the only liquid you can target .

You can also use words of power while within that range . Words of power cause magical effects or spells to emerge from the barrel itself , and can be used as an action . The words of power are :

Fill : The barrel rapidly generates 10 gallons of the designates liquid , filling itself with it .

Absorb : You target , within 30ft of the barrel , up to 10 gallons you can see of a liquid that is identical to the barrel's designated liquid ; the targetted gallons are cleanly pulled off surfaces and containers , then rapidly float their way into the barrel . Alternatively, you suck up fog in a 30-foot cube centered on the barrel , destroying it in the process as it condenses into the barrel and turns into 5 gallons of the designated liquid.

Rain (1/day) : Over the course of the next minute , 35 gallons of the designated liquid falls as rain in a 30-foot cube centered on the barrel .

Puff (2/day) : 5 gallons of designated liquid within the barrel puff up into a 30-foot-radius sphere of fog centered on the barrel . The sphere spreads around corners, and its area is heavily obscured. It lasts for the duration or until a wind of moderate or greater speed (at least 10 miles per hour) disperses it. You concentrate on this ability as if it was a concentration spell , for up to 10 minutes .

Wave (2/day) : You cast the wall of water spell on a point within 60 feet of the barrel without expending a spell slot or material components , making a wall of your barrel's designated liquid appear . If the chosen liquid allows it , the spell's effects on fire and cold damage are maintained . You concentrate on the spell as per the concentration rules .

NOTES

The dimensions were chosen to make sure the barrel would qualify as small while holding 35 gallons .

Bubble (2/day) : You cast the water sphere spell on a point within 90 feet of the barrel without expending a spell slot or material components , making a sphere of your barrel's designated liquid appear .
