Ahh the good old Pyro. It's also the only class feasible to do a Level 1 run too. Not because it's the only class that starts at level 1 (you can attempt similar runs for the base level of each character), but because pyromancies are way too powerful and useful.
Who needs armour when you've got Iron Flesh? Who needs Fire protection when you need Flash Sweat? Who needs weapons when you got Great Fireball? Just upgrade your Pyro's Flame to Quelaana's Pyro Flame +5 and destroy everything in your path XD.
Also, it's always the japanese players doing these things first XD. It was the same with Demon's Souls Level 1 run and, in an unrelated game but with a much higher difficulty level challenge (if not more), Order of Ecclesia Hard Mode Level 1 run (I attempted it, got through it and trust me, as much as I love Demon's Souls and Dark Souls, their difficulty is child's play in relation to it).
