I purchased this and it works very well for weapons with specified attack ranges. The only downside to it is that if you try to use it for a card effect close range melee weapons wont use the normal range of skills and will go right up to the target to use the skill. This is easily corrected if you use the bonus bAtkRange in the script also to set the attack range. I use my item_combo_db to modify my rods to have the effect without having to mess with any actual items (makes updates so much easier).

I use this this format in the item_combo_db to for all my rods:
1601:1601,{ bonus bAtkRange,6; bonus2 bIndOnAtkCast,17,1; }
