Wyrmripper (Dragon Slayer Greatsword)

Rare

You gain a +1 bonus to attack and damage rolls made with this magic weapon. When you hit a dragon with this weapon, the dragon takes an extra 3d6 damage of the weapon's type. For the purpose of this weapon, "dragon" refers to any creature with the dragon type, including dragon turtles and wyverns. This item can be found in the Dungeon Master’s Guide. Made of what appears to be roughly crafted pig iron with a crude leather haft, this enormous greatsword possesses a bold Davek rune at the base of both sides of the blade which reads “Wyrmripper”.
