A massive, single bladed greataxe made out of melted dragon scales. This weapon was forged by the great dwarf forges of old, back in the days where they had to make the forge out of the strongest magic imbued stone so that the fire inside would not melt the entire mountain the forges were in. Whenever you make an attack with this axe, you can call upon the power of any dragon type you wish, (the greataxe has been made out of the melted scales of many dragons), and deal an extra 2D12 damage of that dragons element alongside whatever damage you are dealing otherwise. You gain +4 to attack and damage rolls made using this magic weapon.

Draconic Power. When using the greataxe, you can call upon the power of any dragon to assist you. The attack deals 2D12 damage of your chosen dragon's element in addition to whatever damage it does otherwise. Alternatively, instead of making a usual melee attack, you can cast any Ancient dragon's breath weapon from the greataxe. This consumes 1 charge per use of this action.

Cleave. If you hit a creature with a melee attack roll using this weapon, you can make a melee attack roll with the weapon against a second creature within 5 feet of the first that is also within your reach. On a hit, the second creature takes the weapon’s damage, but don’t add your ability modifier to that damage unless that modifier is negative. You can make this extra attack only once per turn.

Proficiency with a Greataxe allows you to add your proficiency bonus to the attack roll for any attack you make with it.

Notes: Bonus: Magic, draconic creature or dwarf, Heavy, Two-Handed, Cleave
