ZombieHeadz of Mirrah is showing the move set for the Crescent Sickle in Dark Souls 2.
"A sickle with a crescent-shaped blade. This sickle, enchanted by magic, is not intended as a weapon, but rather a ceremonial instrument."
Your stats need to be 18 STR and 30 DEX to power stance Crescent Sickles. (You need 12 INT to be able to use them effectively)
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.
