[Snake]

Just increase the range to 8-9 tiles and call it a day, Dev. The size will probably compensate for how much impact it does (In a non-lewd way). I remember that the only problem with Holy Spark's range was that the skill was an AoE on top of the absurd range.

Holy Arrow is just a basic Shinken with no reach that does magic light damage. So it will be fine with an insane range.
