You do not jump through rings to get the tilt skull in halo 3.

The tilt skull makes weaknesses weaker and strengths stronger. For instance, with tilt on, it will take 8 headshots with a sniper rifle to kill a brute minor on Normal, while it will take 2 plasma rifle bolts to strip the power armor. Tilt also causes unshielded opponents to have a huge resistance to plasma. For instance, an brute minor with stripped power armor can take a full plasma rifle without dying.
