You mean that room behind the Crystal General? If so then, believe it or not, the trigger is...To die. No, I'm being completely serious.

There's no way to progress in the Duke's Archives at that point except for dying to Seath. There is absolutely no way to harm him due to his immortality from the Primordial Crystal. You can just put on a Ring of Sacrifice to avoid losing anything, and if you're afraid of dying to his Curse effect, you can use a Rare Ring of Sacrifice instead, or put on the Cursebite Ring for more resistance to avoid being Cursed. Once Seath kills you, you wake up at a different bonfire in a cell, and the Duke's Archives plot continues.
