Your sim barely makes it back alive. Roll d20.

"But wait, they can't really be ... gone?"3+ Athletic or 5+ Logic can reroll with d20.

If you roll a 15 or higher, your sim escapes their fate and gets to keep their supplies but they are injured. Your sim's skill is a modifier and could be their saving grace.

i.e. A sim with 6 skill points needs to roll a 9 or higher to survive.
