Magical Item – Rare – Horn of Blasting – 12,000 gp

• Standard: You can use an action to speak the horn’s command word and then blow the horn, which emits a thunderous blast in a 30ft cone that is audible 600ft away. Each creature in the cone must make a DC 15 Constitution saving throw. On a failed save, a creature takes 5d6 thunder damage and is deafened for 1 minute. On a successful save, a creature takes half as much damage and isn’t deafened. Creatures and objects made of glass or crystal have disadvantage on the saving throw and take 10d6 thunder damage instead of 5d6.
• Each use of the horn’s magic has a 20 percent chance of causing the horn to explode. The explosion deals 10d6 fire damage to the blower and destroys the horn.
• Attunement: If you are attuned to the horn, the break chance is reduced to 10 percent.
• Relic: If you are a Genasi and attuned to this item, you can pair this item with a worn Air Genasi item, counting both as a single attunement.
• If you are an Air Genasi and attuned to this item, you can use the item without a break chance.

Creatures and objects made of glass or crystal have disadvantage on the saving throw and take 10d6 thunder damage instead of 5d6.
