Bullet Ballet is a gear perk that refills your weapon's magazine after a takedown. It lets you go straight from a silent kill into shooting with a full mag.
Every takedown tops up the magazine of your current weapon, so you never get caught reloading right after a kill.
Wear one of the gear pieces that carry it: Altaïr's Gauntlet, Breach & Clear Gloves. Each piece only takes one body slot, so plan around the other perks you want.
Good for players who mix takedowns and gunfire. Pure stealth players will get less from it.
