Yeah I know that you can easily find which skills works with bows, by assuming that they do, if it's not precisely written "melee only".
But, I want to find out, which DO work with melee.
F.E. Slow Shot can be used while wielding melee weapon, but Piercing Shot, or Long Range(obviously) won't work unless character is wielding ranged weapon.
Another words, solution that you proposed is valid, but to find out opposite thing to what I am after.
