This is a combination of moves that involves a body block and a knockdown attack (counts as 2 melee attacks). A successful Body block Strike against a fellow human does 1D4 damage Plus P.S. damage bonuses, and the opponent is likely to be knocked down. A successful strike always inflicts damage from a shoulder, elbow, or tucked head, unless their opponent Dodges (no damage or knockdown).
The victim who is hit can avoid being knocked down only by trying to maintain their balance and must make a 1D100 roll. A typical Body Block ram has a 50% chance of knocking an opponent down and character with no special balancing ability must roll above that number or fall.
Knockdown Modifier:
Add 5% to the roll the victim needs to exceed for every 5 points of P.S. above 20. [E.g. an attacker with P.S. 30 requires 60% to save getting bowled over.]
Characters with a special balancing ability from a skill, such as Acrobatics or Gymnastics must roll under their current skill level to keep their balance (if the skill is 45% they must roll under 45, etc.) A successful maintain balance means the victim is not knocked down but still loses 1 melee attack action, and takes normal damage. Note: Characters and creatures with Supernatural P.S. and/or greater bulk/weight, or size or speed have an increased likelihood of knocking an opponent down and inflicting greater damage. These special instances are noted under each character description.
Knockdown Penalties:
Being knocked down causes the victim to lose Initiative (if they had it) and 1 attack/action for that melee round, plus they are knocked 1D6 feet (0.3-1.8 m) away from where they were standing at the moment of the attack. A Roll With Impact can reduce damage by half, but counts as 1 melee action.
