Dark Souls 2 Black Dragon Greatsword Tutorial (dual wielding w/ power stance)

A friendly Dragonbro stopped by to demonstrate the Black Dragon Greatsword move set in Dark Souls 2. "In legend, this oddly-shaped long sword is said to be forged from the black dragon's tail. As it is told, the black dragon lost its tail to a brave warrior in a magnificent battle, and the tail was later used to forge several legendary weapons." To power stance two of these, your stats need at least: 38 STR and 24 DEX. Power Stance requires two similar class weapons in both hands. Your stats need to be 150% of the highest STR and DEX requirements of those weapons. See the Black Dragon Greatswords upgraded stats at: http://darksouls2.wiki.fextralife.com/Black+Dragon+Greatsword
