Here, you'll be able to enter into a boss battle against the Collector, who is the one that trapped the Grubs in the first place. Head up through the City of Tears into the Tower of Love (you'll need the Love Key, found in the Queen's Gardens). If you're unsure of which Grubs you've found and which you haven't, you can use a special item. RELATED: Hollow Knight: All Grub Locations There are only 46 Grubs to find in total, so you'll have to find a good percentage of them to earn yourself the Ore. After rescuing 31 Grubs, he'll give you a Pale Ore. For rescuing certain numbers of them, the Grubfather will throw you some rewards, typically Geo. You can earn some really good rewards for rescuing the various Grubs that you can find around Hallownest. Some of your spells are very useful in this fight, and you can use the Howling Wraiths/Abyss Shriek to hit it while it's hiding in the ceiling.

Sticking to the edge of the middle platform can help you avoid Nosk when it charges. It'll charge at you and damage you without stopping, jump around, give off an eruption-style attack, and rain Infection down from the ceiling. These two qualities make it very hard to avoid. It's quick, and it also fills a lot of space in the room. Once you defeat this shapeshifting boss, you'll be able to continue on to find the piece of Pale Ore that you came for. Nosk is a terrifying boss that mimics the faces from the memories of bugs in order to lure them into its lair. In a room to the west, you can break the western wall to continue heading deeper, and eventually to Nosk's lair.

Deep into the southern portion of Deepnest, you'll find a hot spring.

You'll need to defeat a pretty tough boss for this piece of Pale Ore, so prepare yourself accordingly and then head to Deepnest.
