@t2wave Just a reminder, 3 is where things start to become super-human. That would make Adaptive Biology, Plant Physiology, and Chemical Production a 3 as they are all in excess of what even a very gifted person can do. Otherwise you're good to go.
@HeroicSociopath Thanks! Based on the descriptions, I'd probably say that the bombs are only a level 3 whereas the gauntlets and helmet are probably level 2. That'll get easier for all of us as we refine and clarify the tier system. Let me know when you make those changes and you're good to go!
