I created one and Put it out there for a few games I used to play where it had every item listed and you just plugged in how many you had if each item and it calculated everything. Since I dot have a full list for this game, I just inventoried all my stuff and made it sortable alphabetically, by quantity, attack and defense.
Pm me and I'll do it. Depending on your level, $10 may not be enough..$15-$20 may be more like it...what level and how many weapons? Pm me. Once it's done once, it's rather easy to update.
