Upgrading your primary weapon in Hollow Knight requires finding one of the rarest materials scattered across the subterranean kingdom of Hallownest. Pale Ore serves as the essential currency for the Nailsmith to forge stronger variations of your nail, significantly increasing your defensive and offensive capabilities against tough bosses. Discovering all six hidden pieces demands thorough exploration, specific traversal abilities, and the completion of various side activities throughout the game.
Discovering Hidden Ore in the Depths of Hallownest
The vast network of the underground world conceals several pieces of ore within dangerous territories that require exploration. Adventurers can locate one piece in the Ancient Basin area by heading west from the main tram station, though you must defeat two guarding Lesser Mawleks to claim it safely. Another hidden resource rests within the eerie tunnels of Deepnest, tucked away inside a breakable wall directly west of the area hot spring after successfully defeating the boss known as Nosk.
Traversing to the absolute peak of Crystal Peak brings players to a majestic sub-area known as Hallownest Crown. High atop this summit, you will find a valuable piece of ore embedded directly into the pedestal of a grand statue dedicated to the Radiance. Reaching this specific point requires the Mantis Claw, while having the Monarch Wings and Crystal Heart abilities will make navigation much easier.
Earning Valuable Rewards Through Side Quests and Trials
Not all upgrades are uncovered simply by exploring empty corridors, as several characters reward your milestones with this scarce metal. For instance, rescuing trapped grubs for the anxious Grubfather in the Forgotten Crossroads eventually results in a wonderful gift. Once you successfully return 31 grubs to their home, he will throw down a piece of ore as a token of his immense gratitude.
Gathering dream energy provides another reliable avenue to secure the rare forge material during your journey. By collecting 300 Essence using the mystical Dream Nail and returning to the Seer in the Resting Grounds, the ancient moth will hand over a piece. This objective can be achieved quickly by defeating dream warriors or harvesting whispering roots scattered around the map.
Conquering the Intense Arena of Kingdom Edge
The final challenge for combat-oriented players resides within the colosseum located at the furthest eastern borders of the kingdom. To secure the last piece needed for a fully upgraded weapon, you must successfully complete the grueling Trial of the Conqueror. This second arena challenge tests your battle prowess across 17 distinct waves of diverse enemies and shifting terrain hazards.
