Lazarus patch

A vital tool for adventurers, the lazarus patch is a heavy compress laced with antibiotics, coagulants, system stabilizers, plasma, and a one-shot diagnostic suite. If the patch is applied to a character that has fallen to 0 hit points, the user can make an Int/Heal or Dex/Heal skill check against difficulty 6 to stabilize the subject. The more time between injury and application, the less chance the patch has to work. Each round after the first, an additional -1 penalty is applied to the skill check. The patch is no use after six rounds. If the medic fails the first skill check, they can keep trying the check once per round until the victim is revived or time runs out.
