Someone please explain how experiencing a great deal of pain and doing (as far as we know) absolutely nothing in the immediate aftermath is indicative of any sort of "threshold." Bane can obviously cope with a tremendous amount of pain because he spends years in agony and operates through it; Cay Qel-Droma, by comparison, has his arm lopped off and falls to his knees crying for his brother. But since Cay got hurt real bad he has a high pain threshold, right?
Bane was covered in Orbalisks for decades, in constant agonizing pain, until they got removed. Bane was trapped in a sphere of his own lightning, which was potent enough to reduce people to ash, as the orbalisks burrowed deeper and deeper into his body, going down to bone level, while expanding, before exploding inside of his body and releasing a corrosive poison capable of breaking his body down on a molecular level.
In DOE, he describes slight contact with a tendril to be far more painful than anything he has ever experienced by a huge margin, while explicitly citing the aforementioned experience. After having his entire arm severed by a tendril, which is far more than the brief contact I just mentioned, he maintains the mental composure to evoke the ritual of essence transfer.
From this, Bane's pain threshold impresses me more than anyone else's, with the exception of perhaps Sion, who is referred to as "the lord of pain."
