Only 1... I always skip horsefuck valley when playing Dark Souls 2. I'll take 1000 Bed of Chaos and Lost Izaliths over that poorly-designed shithole. Honestly I'd probably also skip the Iron Passage/blue Smelter Demon and Cave of the Dead/gank squad if I were to play it right now. All those areas were designed for co-op so they're pretty miserable to solo.
