There was a time where I regretted my obsession with Undertale…but I did make a semi interesting character that was to replicate Sans in a way. It was a mage who had a curse set upon himself that slowly removed his flesh, soon to only reminisce of his bone, yet still allowing him to live. The more the corruption would spread, the more he’d drift into madness. So that was one of the things we would check up on my character, how bad that sort of “corruption” was spreading, because I gave the DM the ability to choose how much the corruption would spread each time we’d play (We just asked him to keep it at a somewhat reasonable pace). So at the start we’d do a little check in and ask “what part of the body did -fill in my name- lose?” And he’d just let us know and we’d be on our marry way.
