Coated quiver of Fiery Doom

Wondrous item, rare (requires attunement by a fighter or rogue)

This distinctive orange-yellow and dead-black quiver is painted with a burning skull.

Radiates: Evocation and transmutation magic.

Power: When you place up to 12 nonmagical pieces of bow or crossbow ammunition in this quiver, it becomes +1 ammunition coated with fire magic. You must leave it untouched inside the quiver while you complete a long rest or the magic fails.

Once coated, you deal an extra die of fire damage for your ammunition type (hand crossbow and shortbow ammunition deals 1d6, light crossbow and longbow ammunition deals 1d8, and heavy crossbow ammunition deals 1d10). If you target an unoccupied 5 foot square, flames erupt in that square and continue to burn for 1 minute. Any creature that moves through or begins or ends its turn in that fiery square, must make a Dexterity save or take 1d4 fire damage. If you target a flammable object with this ammunition, it ignites. This ammunition is destroyed when used.

Limit: You cannot sell, discard, or give this magic ammunition to others. If you do, it loses it magic.
