Double Axe (5e Equipment)
From D&D Wiki
Martial Melee Weapons
This polearm has a reinforced wooden haft with a double-bladed battleaxe head at each tip.
When you take the Attack action and attack with the double axe, you can use a bonus action to make another attack with the double axe. If this attack hits, you deal 1d6 slashing damage. You don't add your ability modifier to the damage of the bonus attack, unless that modifier is negative.
If you have the double weapon master feat, you deal 1d8 slashing damage with both the double axe's normal and bonus attack.
