G-Force 199 (重力物体１９９, Jūryoku Buttai 199?, lit. Gravity Object 199), also known as 199 Gs, is a recurring ability in the series. It is the summon ability of Atomos, which deals fractional damage on all enemies.
G-Force 199 is the ability of Atomos, originally costing 128 MP to cast before Garnet loses her summons and then 32 MP when she relearns Atomos. G-Force 199 damages an enemy equal to a certain percentage of their Max HP capped at 9,999 HP, and will not work on bosses. The damage formula for G-Force 199 during the full animation and half animation is as follows:
- Damage = [((30 + Amethyst) * Target Max HP) / 100]
- Damage = [[((30 + Amethyst) * Target Max HP) / 100] * 2 / 3]
199 Gs is the ability of Atomos. For 50 seconds, whenever the summoner receives HP damage, they gain Bravery equal to their opponent's Bravery prior to the attack.
g-force (with g from gravitational) is a measurement of the type of acceleration caused by mechanical contact-forces between object surfaces that indirectly causes weight.
