[RPG] Is the Decanter of endless water unlimited

dnd-5emagic-items

I have given my party a decanter of endless water (was part of an in game joke, a dwarf was left the amulet of the drunkard and a decanter of endless water to make sure he never was without a drink).

At the time it felt like an innocuous magic item to give but then the campaign took a left turn into the fire plane.

So I wanted to confirm I am letting my party use the tankard correctly, an action and a reaction to say the trigger word and aim the geyser (30 gallons) which does 30 cold damage to a fire elemental (plus the potential of the bludgeoning damage) and, more importantly, can be used over and over again with no limitations?

Is that correct?

Best Answer

Using your action and bonus action, the Decanter can deal 30 cold damage to a fire elemental each turn.

You’ve mostly got the right idea, except aiming the Decanter’s geyser is a bonus action, not a reaction:

As a bonus action while holding the decanter, you can aim the geyser at a creature you can see within 30 feet of you.

Since the geyser is 30 gallons of water, a fire elemental would take 30 cold damage:

Water Susceptibility. For every 5 feet the elemental moves in water, or for every gallon of water splashed on it, it takes 1 cold damage.

There are no limitations to how often you can use the Decanter’s geyser, except the action economy that restricts you to a single bonus action per turn.
