What does the i would have been your daddy skull do?

Answer 1

The IWHBYD skull has no game-play effects, however it does change certain NPC dialog throughout the campaign story. The dialog chosen is random. Sometimes it can be humorous, and other times just slightly different than the script dialog.

Answer 2

what the last guy told u is wrong the skull is in the mission: The Covenant; and is located in the hall with the seven blue holograms(spread out in three sections). You'll need to jump through the rings in the following order (1 is close to the entrance and 7 is near the prophet of truth): 1, 3, 4, 6, 7, 5, 4, 6, 5, 4, 5, 3, 4.note that each ring hums a different note--- the correct sequence plays out the halo theme. if done correctly, all the rings will start flashing, and you'll hear the tune, the skull will appear on the bridge to the prophet of truth.this can be done before or after the prophet scene, but make sure you've cleared out the enemies first.
