Improved Knockdown Feat 10
Source Pathfinder Core Rulebook
Prerequisites Knockdown
You can dash your foe to the ground with a single blow.
When you use Knockdown, instead of making a Strike followed by a Trip, you can attempt a single Strike. If you do and your Strike hits, instead of rolling a check for your Trip attempt, you automatically apply the critical success effect of a Trip.
If you used a two-handed melee weapon for the Strike, you can use the weapon's damage die size instead of the regular die size for the damage from a critical Trip.
