Grand Dad

The Grand Dad is a Post-Moon Lord broadsword that drops from the Moon Lord. It is the rare variant of the Grand Guardian. Whenever the Grand Dad contacts a non-boss enemy, their defense is reduced to zero and their knockback resistance is set to -600%. It also has an exceptionally high knockback stat and size.

Tips

 * The knockback makes this weapon a good tool to keep an enemy with high health away.

Trivia

 * Its name and tooltip, as well as the "7" on its sprite (and the 777 base damage and 77 knockback), are a reference to a meme known as "7 GRAND DAD," a Chinese bootleg copy of The Flintstones: The Rescue of Dino & Hoppy for the Famicom system and popularized by Vargskelethor a.k.a Joel from Vinesauce, and SiIvagunner.
 * The word "Yeet", which is present in the tooltip, is internet slang that means "to throw at high velocity".
