I just started playing this about .. an hour ago. I understand most of it so far, it's not that far off from other tower defense games I've played, just a bit more hands on .. but when I'm looking in my Item Box, every item seems to have a number on it. When you click on that item, that same number is in a blue crystal type thing on the right. I thought it was something like, higher numbers are higher quality .. but when I check the wiki, quality seems to only be denoted by the name of the item. So .. what the hell is that number? I have like 10 weapons for my guy, and I'd sorta like to decide on one to level for a bit .. but this one part seems to be confusing the crap out of me.
