In Hollow Knight, upgrading the Nail is an essential part of the game. Without upgrades to the Nail, you will struggle to beat some of the later bosses, so you will need to time your upgrades well in order to match the game’s difficulty.
Nail is the term used to describe the type of sword in the game, which is what the main Knight character wields – known as the Knight’s Nail.
How to upgrade the Nail in Hollow Knight
You must find the Nailsmith in the City of Tears. Once discovered, you will be able to trade Geo and Pale Ore to upgrade the Nail.
If you can’t find the Nailsmith, follow this guide which shows you the exact route to take.
Finding Pale Ore is what will allow you to reach the third and fourth Nail upgrades, and is a lot trickier than collecting Geo, which is simply from defeating enemies. There are only six pieces of Pale Ore in the game, all of which are required to reach the final upgrade of the Pure Nail.
