This is an easy & fun build!! Don't look into these rules because it's not going to work out in your favor. If it's not stated in the rules, then you can't do it. As always, I'd love to have everyone's input. I'm trying to make classes for everyone & think this class will be a hit. Thanks for y'all's support.
