Currently, a team mate must heal a fallen caver. However, this can make for a really dull game for someone if their caver is/becomes isolated. To counter act that, we can use a variable skill check for becoming conscious, with 1 health:
- first turn after falling unconscious, must roll a 6 to wake up - second turn, must roll a 5 or a 6 - third turn, must roll a 4, 5, or 6 - fourth turn, must roll a 3, 4, 5, or 6 - ... and so fourth
Worst-case scenario, after six turns the caver will be awake again.
