Damage multiplier - Optional damage multiplier for this specific hit scan

Overrides - These overrides are crucial in AACS, they are use to change the Hit Type, Damage preset, Launch or Direction for this specific hit scan.

Allow Multi Hits - By default a hit scan can only damage once, but with this option an interval can be chosen for it to be able to hit again.
