Potion of Destruction

Make a ranged attack at a space you can see, using
STR/DEX+PROF (DC 10). On a failed throw,
refer to DM's excellent missed thrown device rules.
The blast will do 3D6 fire damage to everything
within the 15 foot radius that fails to make a DEX
saving throw (DC 15). On a success, the victims
take half damage.
This is a single use item.
Upon reflection, all explosions are blasts from the past
