So, I'm getting back to my Planet Mercenary ruleset. I got my hands on a copy of the player sheets, as filled out for the Gencon adventures and I found that they notate the weapons a bit differently.
The "Sledgehammer" has three forms of attack, so they put it over three rows. My guess is that I can probably do something involving adding additional picks to the weapon and then iterating over some higher category which holds both "weapon" and "damage", but I haven't quite managed to wrap my head around it yet.
Any advice?
