The game manual states:
With powerful, penetrating shots, staffs excel in long-range sniping. Although weak in close combat and lacking homing performance, staffs feature shots that grow in power over distance.
According to this, the damage dealt by Staffs should increase the further away you are from your opponent. However, after experimenting in the training mode this doesn't seem to be true. For normal shots, distance makes no differences. For charged shots, damage actually increases the closer you are to your opponent. Obviously something is amiss here. I'm hoping this is simply a bug in the training mode, but since damage done isn't reported during missions it's hard to test how much damage my staff is doing.
Does staff damage decreases the further you are away from your opponent, or, as the manual states, does damage increases with distance, and there is simply a bug with the training mode?
