Old Nail (Conquest) - Official Terraria Mods Wiki

The Old Nail is a Hardmode Sword sold by the Skeleton Merchant in hardmode. It behaves like the Arkhalis. Unlike the Arkhalis, the Old Nail has a secondary attack and a "Hollow Gauge" for it. The hollow gauge acts as a charge for the second attack, when maxed you can perform the second attack. The hollow gauge builds charge by hitting and killing enemies.
