Don't get me wrong, I enjoy Nightcrawler, it just gets frustrating dying constantly. I need to get him to 60 and geared up. Right now I only have one unique for him.
yeah, he does die a shit-ton. even at 60 and at the time with a full set of his generally best uniques (not great rolls), I was getting my ass handed to me. And regardless of gear, if you have the misfortune of standing in an AoE bomb at the wrong time--like second stage Doom unloading everything in one spot with punches, power cosmic, flame circles; or that one annoying room in cosmic Kurse where all the blues spawn and shoot you), you will die fast. It's kinda funny--especially when you inadvertently teleport onto their targeted AoE spot. Not much you can do about that
A couple of things really help: A very good Advanced Crimson Crystal of cytorrak, which is the type ofartifact you will probably always find a place for on your favorite characters. I also have an adv Super Soldier Serum--mainly because I'm not getting much else that I would put on him (the Kursed Gem or Hand of Doom, which I have yet to drop, and may never will), but the SSS is a pretty good artifact overall if you need survival. I only now replaced my Scrolls of Pama with a Pym Shrinking (acquired in trade), but Pama is very useful--I dont' mind depending on orb drops with someone like NC< because it's easy enough to teleport out and back into fight to pick up anything you need.)
Uniques like Nate Grey's Psionic and NC's Great White Shark, well rolled, are difference makers. If you think you will play him a lot, consider an Excalibur as legendary. I think more and more are using that over Gungnir on NC, because the defense is so much more important in cosmics and, I suppose, Raids. I already had a half-leveled Gungnir and didn't want to bother replacing it.
Starting over, I would definitely put Excalibur on him; the damage loss is very minimal compared to the major gains in defense with Excalibur. I also have a stack of now 112 or so Lemuria on NC. It's basically the only relic you want to put on him. For costume core I have a 400 LoH and + strength (I like strength because it reduces cost of physical powers--all of NCs powers are physical; and now almost all of them are also melee). though, with 4 strength, it's weird seeing NC pick up cars every now and then...
