I'm willing to make my Excel spreadsheet available to any who ask. I just need an email to send it to and I'll use my Yahoo email to send it to you.
My skill tracking is on one tab (multiple shards). Target, current, difference, when last played, scrolls eaten, STR-DEX-INT tagets and current. Lock status noted as needed.
Armor/stats are on another. On that it's by character per tab as upper part is current resists (real and capped) and mods. Lower part is where I alter things by entering stats and mods for pieces I am looking at buying.
By seeing the change between now and forecast, I can determine of I should make the purchase or not.
