Niv - Survives Bolas' attempted mind destruction

          "Enough," Bolas growled, pressing his other palm flat against Niv-Mizzet's skull. Bolas's orange eyes went jet-black, and the power of his mind surged through the link between them.

          It would have been enough to burn a mortal's mind to ash in moments, but Niv-Mizzet was no mortal. He was the Firemind, fifteen thousand years old, and in that time he had learned a thing or two. Bolas's mental assault, a black tide of violence and oblivion, slammed against the mental barriers Niv-Mizzet had erected. For a moment his defenses strained against the waves, but when Bolas's power ebbed Niv's wards were still intact. Bolas recoiled, like a man bouncing off a door he expected to be open, and Niv-Mizzet used the opportunity to surge out of his grip, raking Bolas's chest with his rear claws as he scrambled back into the air.
