Joostmod/Old Nail

The Old Nail is a Pre-Hardmode melee weapon that drops from destroying certain ambient objects underground or the 'fake' sword in most Enchanted Sword Shrines. In combat, it works similar to the Arkhalis, but lacks the autoswing. When attacking from below, the player will bounce on top of enemies.

Trivia
The Old Nail and its upgrades are references to the indie game Hollow Knight. It is the player character's starting weapon.
