Halo 3 Rings Skull is the last skull you'll find in the campaign. It's also meant to be the hardest, as the process for getting it is rather cryptic. You'll be rewarded with the opportunity to hear unusual dialogue. Here's how to get the last skull in Halo 3.

Halo 3 Rings Skull: How to Get on PC

Right after you're betrayed by the Flood and take them all out at the end of the game, don't jump down the elevator vent yet. Make sure all of the enemies on the floor are gone. From the elevator, turn and face the holographic rings. You'll have to jump through each ring in a specific order.

The ring closest to you is 1, and the furthest is 7. Jump through the rings in the following order: 4 6 5 4 5 3 4.

If you've done this correctly, the skull should be waiting for you at the control console. If you didn't get it, you can go back and start the sequence again without starting over the level.

This skull doesn't provide a point multiplier like most of the other skulls, but it does provide a humorous bonus. It will reverse the dialogue rates for NPCs.

There are rare pieces of dialogue that are spoken by NPCs in the game. You can trigger these lines occasionally, but the skull will make it so these weird lines are spoken at the rate the normal dialogue comes. It will also unlock new dialogue for them as well.
