Halo 5 IWHBYD Skull Location in Mission 1
The Halo 5 IWHBYD skull in mission 1 is right after you have to use your “Spartan Charge” for the first time. Follow the mission path to the big gate with the blue lights.
Jump onto the rocks left to it and you find the IWHBYD skull sitting on the edge of the cliff.
Although this skull always meant a huge headache, because of the ridiculously difficult hoops you had to jump through, it is a bit disappointing to see it lying around without any challenge here.
This skull will make rare combat dialog more common when activated.
