Clawline is a special ability you can unlock in Hollow Knight: Silksong. It lets Hornet throw her needle at enemies or certain objects and then pull herself toward them. This helps you swing across big gaps or reach places that are hard to get to. You will find this ability in the Underworks area. Look for a place called The Cauldron, there, you will see something called the Clawline Idol. Interact with it, and you will unlock the Clawline ability.
How to Get Clawline Harpoon
To unlock the Harpoon ability, the first thing you will need is the White Key. You can find it in the Songclave area.
Now use the key to unlock Coral Chambers and get access to WhiteWard. From there, keep progressing through White Ward until you reach the Underworks, but make sure you’re on the right-hand side of the Underworks, not the left side that you may have unlocked earlier in the game. You are going to be on the right, just after leaving White Ward.
Start from the resting bench at this point, and head left. Go down, activate the switch, then ride the wind upwards. Head through the door on the left, and keep going down again. Try your best to avoid the enemies as you descend, there are a few along the way.
At the bottom, you will land on a lava platform. Keep going down and then prepare to head right. Avoid another enemy here, then quickly jump up onto the next platform, it disappears right after you touch it, so be fast.
Now you will reach a tricky section where you need to make your way across lava using small platforms. Time your jumps carefully and keep moving.
You will eventually reach another part with two enemies. You can either fight them or try to run past. After that, keep jumping across platforms, climb up the wall, and go over to the next area. Be careful here and keep heading up.
At this point, you will be close to the Harpoon. You can detour downwards to grab a metal shard, but it is recommended to go for the harpoon first, as it will make everything else a lot easier.
From here, go through the doorway at the top. You will enter a parkour section where you need to jump across a bunch of wooden platforms. Use a jump + glide rhythm: Jump, glide – then repeat it a few times. Right at the end, do a dash to reach the final platform. And that’s it. This is where you will unlock the Clawline ability.
How to Use a Clawline Harpoon
You will be using Clawline a lot in areas where platforms are far apart and hard to reach with regular jumps. You can also use Clawline to zip into enemies and hit them with a strong, focused attack. To use it, just hold the designated button (like R2 in the reveal). You can now also use the L2 button to fire your harpoon and launch yourself toward the spot you aim at. It is useful for both combat and movement.
