Oxygen-Points, Explanation of:

     Your character’s MENTAL-STRENGTH x3 will be a character's Oxygen-Points (O.P.). This is how long you can hold your breath.

 

Holding your breath:
      While a character is holding his or her breath. oxygen-points will be taken off. The number of oxygen-points that will be taken off depends on whether a successful avoidance-roll vs. “Breath” is rolled or not.
     Look at the following chart to see the amount of oxygen-points that will be lost, PER TURN, while holding your breathing:

 

                                                               Avoidance-roll vs.               Avoidance-roll vs.
Activity vs.                                             “Breath” successful.           “Breath” unsuccessful.
oxygen-point loss:                                 O.P. expended per turn:     O.P. expended per turn:
Motionless:                                           1-D4                                     2-D4

Moving about casually:                        1-D6                                     2-D6
Swimming, Running, Fighting, etc.:     1-D8                                      2-D8

 

     Once oxygen-points reach zero, a character will pass out. When oxygen-points reach, in the negatives, equal to a character’s full amount of oxygen-points, death will occur. In other words, if a character has 90 oxygen-points, he or she will die if they recede below zero to -90.
