Searing, white, and incredibly dizzying pain racked my body from head to toe, feeling nothing but pulverizing pain racking through every organ and member and fiber of my being was not a pleasant experience.

The Golden Titan's Madness wasn't without faults, mainly the fact that you completely fall into madness unable to recognize friend from foe, but that's on purpose, the purpose of falling in madness and denying all and any existence in front of you was mainly to stop this body destroying the sense of anguish that happens when the Titan's body emerges.

The cells on one's body are forced to split and multiply consuming incredible amounts of Qi to do their job, and that comes with the feeling that every bit of your body is getting torn by the passing second.

The madness helps in numbing that pain by focusing it into power and aiming it at anything in front of you. For any other sane man, this pain would instantly kill them or make them go truly insane.
