You jump through the rings in this order (1 is closest to the elevator, 7 is closest to where Arbitor kills the prophet). 4,6,5,4,5,3,4. If you do it correctly, the rings will start to flash. Then go back to where Arbitor killed the prophet. The bridge will be down and a skull will be there. : ). Good luck!
You're probably jumping through the rings in the correct order, but if you are touching the rings the skull will not appear. It also has to be on Normal or harder difficulty.
I Would Have Been Your Dad (IWHBYD)
it is very complicated to get the skull, you have to watch videos on how to get the skull
i DONT KNOW FIND OUT YOURSELF
You Don't Have To Finnish The Level When You Pick Up The Skull. You Only Have To Finnish The Level "The Convent" When You Get The Skull "IWHBYD" Or " I Would Have Been Your Daddy" To Get This Skull You Need To Go Through The Rings In This Order 4 6 5 4 5 3 4.
it is really simply in fact.All you have to do is jump through the rings until after you kill truth.After you killed him and the flood jump through the rings in this order[1 being closest to the begining (where the giant flood are with you)and 7 being the closest to truth.]4 6 5 4 5 3 4if done correctly the rings will light up and the skull will be on the bridge closest to truthcerealkiller666 out...
The iwhbyd skull makes Your enemies (the covenant) Use more melee Attacks
I believe you are missing the IWHBYD (I Would Have Been Your Daddy) skull. Pudding 101 answer: You get it from the Covenant level after you kill truth. (You have to jump through the rings in the order 4654534)
You need to jump through the rings (I assume you know what rings, if not, they are the large rings at the end of the level The Covenant that you pass while advancing on Truth with the flood.) in this order:4-6-5-4-5-3-4There are seven rings. Number 1 is the ring closest to the entrance, number seven is the ring closest to where Truth dies. You may need to jump through multiple times, Halo just randomly fails and doesn't count it sometimes, even if you do it perfectly. You may also need to wait until every single enemy has been defeated (including all the flood, once they turn against you). When you sucessfully jump through the rings in the correct order and Halo registers it, they will light up. Believe me, when it works, you're gonna know.Here is a guide (with pictures), in case any further info is needed: http://www.halo3planet.com/halo-3-skull-locations/iwhbyd-skull/
