Accuracy glitch
The accuracy glitch, more commonly referred to as the SNS glitch, is a glitch that allows the player to cause an attack in a combo to have the accuracy of a later attack.
If a second or third attack in a combo has begun, and the previous attack has not hit the target, the previous attack's accuracy will be updated to have the accuracy of the following attack.
This is most easily achieved with projectile-based weapons, such as slicers and handguns, but it can be performed with certain melee weapons as well.
Example
If a player uses a special attack with their slicer, and then uses a normal attack before the special attack connects with any enemy, the special attack will have the accuracy of the second normal attack, greatly increasing the chance of the special attack connecting.
