Hey TheMelonofTruth,
Sorry about the delay, you probably have it figured out by now, but here’s my whole BP in case you need it. I made it from the third person BP.
Things I did not mention in the first post, make sure you set the bone in the “Transform Modify Bone” node.
I added a + node between the World Direction and the final rotation because the head would rotate but not toward the axis I wanted.
Enjoy

This is something I added in the player character BP so I could see my mouse in game and debug properly
