You've almost got it. There are a couple of ways of doing the "to hit" roll, but I think we're going to keep it as a body contest as 1d10 versus body stat would make actually hitting someone too much of a chore.<br/><br/>So Player A is attacking Player B. Both players roll 1d10 + body + applicable skills. If Player A has a higher total, they hit. If B does, they miss and Player B takes no damage. If Player A hits, Player A rolls 1d10+body+power (or xd10 for energy blasts) to determine damage. Player B then subtracts body + armor from that number (this is what you had confused).<br/><br/>So, if I hit Warhorse, you take the damage total (20) and subtract her body (10) plus armor (4), meaning she takes 6 potency damage.
