Knockdown
Type of Feat: General
Prerequisite: None
Required for: Improved Knockdown
Specifics: A character with this feat can attempt to knock his melee opponents to the ground. The character makes an attack roll at -4, and if successful the defender makes an opposed discipline check against the character’s Attack Roll. If the character wins, the defender is knocked to a prone position.
Use: Selected
Prone characters cannot attack. Characters receive a +4 bonus to attack prone opponents in melee, but a -4 penalty to attack them with a ranged weapon. A character can only make a Knockdown attempt on opponents that are one size category larger than himself or smaller. The opponent gets a +4 bonus on his opposed check for every size category he is larger than the attacker, or a -4 penalty for every size category he is smaller.
When attacking a larger opponent, you get a +1 bonus to your attack roll. Thus you effectively suffer only a -3 penalty when trying to knock down larger opponents.
Monks receive this feat for free at level 6.
