OOC: Because everything you threatan with he has seen before. Karandras had fought Necrons, with mastery over the physical universe, daemons in the warp and gibbering monsters, numberless hordes of Tyranids from beyond the edge of the galaxy, lightening raids by Dark Eldar to torture and kill. He has died over and over again, rent apart by monsters, cut down by firing lines. True Rune means nothing to him, Farseer's use runes and know that such a thing as truth is a lie. Necrons are also an ageless enemy of the Eldar. Also he doesn't believe weapons should be wielded by unworthy. 10,000 millenia of fighting wars in real space and warp space have hardened him even more so than a standard Exarch. He also is fearless. He won't stand down until he has taken a measure of who he fights. I could go on. karandras is my second favourite Phoenix Lord. Threats of power hes heard millions of times over just don't phase him at all. He has every right to his knowledge since he invented a whole style of fighting. Stats don't phase over either but its what I base how fast he is, how good his armour is and how easy he would hit. Seriously I have so many more reasons.
