I couldn't use the spreadsheet at all, the text was miniscule and I could not get it imported into excel (I hate the new version, probably PEBKAC error). I just keep the first page on this post open and search with control-f to see if I want to keep an ingredient or junk it.
I wish the crafted items didn't all have such high requirements, seems like you cant really do crap till 3 or 4 CL which is a ways into the game.
Any of the rest of you have one guy doing crafting and a different one on blacksmithing? My Jahan is a mage generalist and I couldn't afford to raise both on him
