Din's Fire (5e Equipment)
From D&D Wiki
Wondrous Item, rare
This item appears as an eight-sided semitransparent crystal, at the center of which is an orange sphere that dimly glows and swirls like molten rock.
While you hold this crystal, you can use your action and expend 1 charge from this magic item to cast Din's fire (DC 15). The effect lasts for its full duration without requiring concentration, and you cannot choose to end this spell prematurely.
