4th job Single Target DPS

The mirrored hits are simply 60% of the dagger/blade's damage range, nothing stacks on top of that. Maybe final cut was 2x damage earlier, but the way it works now is just +200% applied to every non-mirrored hit. You can probably look for some screenshots or videos to math it out, should be easy because the mirrored hits take the same random damage range number as the regular bottom hits.
