Weapon (longbow), legendary (requires attunement)

This scorching bow sends searing missiles raining through the air like a devastating eruption. You gain a +3 bonus to attack and damage rolls you make with this magic weapon. When you make a ranged attack with this weapon, you can add your Strength modifier to attack and damage rolls instead of your Dexterity modifier.

This weapon has 10 charges and regains 1d10+3 charges after a long rest. While you are attuned to this weapon, if a creature other than yourself touches it, this weapon is considered to be under the effects of the Heat Metal spell.

Ashfall. As an action you can spend 3 charges to fire a piece of nonmagical ammunition from this weapon at a point within 120 feet of you and create a 20-foot radius cloud of volcanic ash centered on the point. Each creature within its area must make a DC 15 Constitution saving throw. On a failed save, a creature takes 2d6 fire damage and 2d6 poison damage and is blinded for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. On a successful save, it takes half as much damage and isn't blinded.

Lava Plume. When you make a ranged attack with this weapon you can spend any number of charges to have your ammunition become like molten slag. On a hit, the target takes 1d10 fire damage. Hit or miss, the ammunition explodes in a ball of molten lava. The area of effect is a sphere whose radius is 5 feet times the number of charges spent. The target and each creature within the area of effect must make a DC 17 Dexterity saving throw. On a failed save a creature takes 1d8 fire damage and 1d8 bludgeoning damage per charge, or half as much damage on a successful one. Flammable objects that aren't being worn or carried within the radius are ignited.

If you spend 8 or more charges to use this property, roll a d10. On a 1, this weapon crumbles into ashes and is destroyed. In 1d10 days, a random volcano on the same plane of existence on which the weapon was destroyed erupts as the weapon reforms within.

Fire. Searing the land. Plumes of endless smoke blot out the skies as the seas roil and churn. With every passing second, more of the earth vanishes beneath an avalanche of ash and lava consuming all before it. A hellscape made manifest upon our world, forces beyond our control, the end of times descends one fiery projectile after another.

Now, harness that might. And let your enemies never forget; nothing stands before the molten fury of the land.
