The Grand Dad was a Godseeker Mode broadsword that dropped from the Moon Lord in Malice Mode. Whenever the Grand Dad contacted a non-boss enemy, their defense was reduced to zero and their knockback resistance was set to -600%. It also had an exceptionally high knockback stat and size.
The Grand Dad's knockback resistance removal could affect enemies that are immune to knockback.
The defense and knockback resistance removal did not affect enemies with no contact damage or most event minibosses.
Tips[]
The knockback made 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), were 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".
