Giant Slayer Battleaxe

You gain a +1 bonus to attack rolls and damage rolls made with this magic weapon.

When you hit a Giant with this weapon, the Giant takes an extra 2d6 damage of the weapon's type and must succeed on a DC 15 Strength saving throw or have the Prone condition.

Topple (Mastery): If you hit a creature with this weapon, you can force the creature to make a Constitution saving throw (DC 8 plus the ability modifier used to make the attack roll and your Proficiency Bonus). On a failed save, the creature has the Prone condition.

Versatile: A Versatile weapon can be used with one or two hands. A damage value in parentheses appears with the property. The weapon deals that damage when used with two hands to make a melee attack.
