I really like these. I'd use both. We may have to discuss my using your creations at some point!
(You need to square the XP values - there's a new XP system in a thread here. I can't wait to get all these various changes out to everybody on a single document!)
Do I understand this right? If I square the yeti's XP it will go from being 30 to 900 right (30*30)?
