When Nix is used as Snow'sEidolon, she will automatically activate ATB Charge when her ATB gauge is below 60% and she is in range of her target. It causes the charge rate to increase to 1.5x the normal speed
ATB Charge appears as a defensive ability. It has an ATB cost of 5 and hastens the restoration of Lightning's ATB gauge. Her physical and magic resistances are reduced by 100% while the ability is active.
