Part 2 0f 2; part one here.
For medium and small creatures:
For use when:
1] A hit is scored with a missile weapon***a firearm or an energy weapon*.
2] A critical hit (natural 20) is scored with a muscle powered melee**weapon.
3] when a character with 0 hit points is hit with any weapon.
1. Minor Wound: 1d4 days to heal [-1 to all die rolls and - 1d4-1 to movement rate during the recovery period].
2. Major Wound: 2d8+2 days to heal [-3 to all die rolls and -1d6+1 to movement rate during recovery period].
3. Grievous Wound: d30 +10 days to heal. [-6 to all die rolls and movement reduced to 1 during recovery period]. Note: A character with a grievous wound must be stabilized within 10 rounds or make a successful saving throw otherwise the wound becomes a mortal wound, and all related conditions apply.
4. Mortal wound: Save or die. A successful save reduces the damage to a Grievous Wound with doubled recovery time. A failed save results in death in 1d6-1 rounds. AT THE REFEREE'S DISCRETION dead character may be healed by miraculous means (super science or magic) for 1d100 rounds after death.
Cowering: when fired upon with missile weapons***, an unsurprised character may hide beneath a large shield and will, in the case of a normal hit, only take normal hit point damage (e.g. 1d6 from an arrow). Critical hits are considered to have pierced the shield and result in a roll on the wound table. Whilst cowering, a character may move 1/4 the Normal rate.
Optional rule: Characters with Major or Grievous Wounds who engage in strenuous activity (e.g. combat) prior to the end of the recovery period must make a saving throw. A failed save resets the recovery period back to the beginning, and in the case of a grievous wound the character immediately becomes unconscious.
This is simple table; the lack of descriptive text is intentional. Description and nuanced effects should be determined by the Metal Master and/or the players. For example, if a hit inflicts a mortal wound on a character and the character successfully saves vs death and has the severity of the wound reduced to grievous, the referee may rule that a limb or an eye has been lost, a terrible scar inflicted, or that a complete recovery is eventually made. This should be situational and be determined on a case by case basis- often by fiat.
