Tumble Defense
Knights of the Old Republic, page 35.
You can use your melee weapon to hinder acrobatic enemies.
This feat is a bonus feat for the Jedi and Soldier classes.
Prerequisites: Proficient with melee weapon used.
Benefit: When an opponent attempts to tumble through a square you threaten with a melee weapon, add your base attack bonus to the DC of the Acrobatics skill check made to tumble. If the target fails the Acrobatics check to tumble, you can make an attack of opportunity against that opponent as normal.
Special: You cannot use this feat when you are flat-footed.
