A magic item for Dungeons & Dragons fifth edition.
wondrous item, uncommon
This carved pumpkin casts bright light in a 5-foot radius and dim light for an additional 5 feet. After 10 days, the pumpkin withers and its light is extinguished. If a creature is killed in the bright light when fewer than 10 days remain, the blazing jack-o’-lantern burns for 1 day longer.
While it burns, you can use your action to throw the blazing jack-o’-lantern up to 20 feet, shattering it on impact. Make a ranged attack against a creature or object, treating the blazing jack-o’-lantern as an improvised weapon. On a hit, the target takes 2d6 fire damage.
A warlock or necromancer may create a blazing jack-o’-lantern by performing a special 1-hour ritual. The ritual uses a pumpkin, 25 gp worth of ruby dust, and requires the caster to expend a spell slot of 1st level or higher.
