Improved Trip

You have a knack for putting your opponents on the ground.

Prerequisites: BCB +1

Benefit: You gain a +4 bonus on your Strength check to trip your opponent.

If you trip an opponent in melee combat, you can immediately spend a reaction to make a melee attack against that opponent.

Finally, you do not provoke a reaction attack when you attempt to trip an opponent while unarmed. 

Normal: Normally, attempting to trip an enemy provokes a reaction attack from them.
