Wondrous item, rare · 2024 version below
While a fire burns in this brass brazier, you can use an action to speak the brazier's command word and summon a fire elemental, as if you had cast the conjure elemental spell. The brazier can't be used this way again until the next dawn.
The brazier weighs 5 pounds.
The 2024 Dungeon Master’s Guide revised the magic items, and the SRD 5.2 carries the new text. What changed:
Same rarity and attunement; the text is reworded for the 2024 rules glossary.
While you are within 5 feet of this brazier, you can take a Magic action to summon a Fire Elemental. The elemental appears in an unoccupied space as close to the brazier as possible, understands your languages, obeys your commands, and takes its turn immediately after you on your Initiative count. The elemental disappears after 1 hour, when it dies, or when you dismiss it as a Bonus Action. The brazier can't be used this way again until the next dawn.
