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 attacker makes an opposed Strength check. If the character wins, the defender is knocked to a prone position.
Special: Characters can only activate one Special Ability per round. This includes Demoralize, Feint and Tumble checks, as well as Animal Empathy, Called Shot, Circle Kick, Disarm, Knockdown, Pick Pocket, Reckless Blow, and Shield Bash abilities.
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.
Notes[]
Monks do not receive this feat for free at level 6 (changed from vanilla NWN). They instead have access to it along with a variety of bonus feat options once per rest via their Monastic Art from level 4 onwards.
