D&D Stuff: Kicking Ass

I always thought that Improved Unarmed Strike sucked. My reasoning: who would bother taking it to do 1d3 points of damage with an unarmed attack when they could take a level of monk and grab a bunch of other benefits

Martial Arts Proficiency [GENERAL]
You are a skilled martial artist.
Benefit: Your unarmed attack deals 1d6 damage if you are large, or 1d4 damage if you are small. You take no attacks of opportunity for attacking unarmed. You lose the benefit of this feat if you are wearing medium or heavy armor.

Improved Martial Arts [GENERAL]
You are a greatly skilled martial artist.
Prerequisite: +5 BAB, Martial Arts Proficiency
Benefit: Your unarmed attack deals 1d8 damage if you are large, or 1d6 damage if you are small. You take no attacks of opportunity for attacking unarmed. You lose the benefit of this feat if you are wearing medium or heavy armor.

Arse Kickin' Time [GENERAL]
Sometimes, you just go for it.
Prerequisite: Martial Arts Proficiency
Benefit: You may spend 1 action point to activate this feat. For a number of rounds equal to 1/2 your character level, you gain a +2 bonus to attack and damage with unarmed attacks, a +5ft bonus to speed, and a 19-20/x2 critical rating with unarmed attacks.

Absolute Bastard [GENERAL]
You are an absolute bastard, and follow no rules or honor in combat
Prerequisite: Nonlawful alignment

-You are attacking in a surprise round.
-You are making a sneak attack.
-Your opponent is unarmed.
-Your opponent is confused, shaken, panicked, or terrified.
-Your opponent is prone.
-Your opponent is retreating or fleeing.

One Fist Behind My Back [STYLE]
You fight with one hand as well as you would with two.
Prerequisite: Martial Arts Proficiency, Improved Martial Arts, Weapon Focus (unarmed strike), Two-Weapon Fighting
Benefit: Effectively, one hand of yours is treated to be two weapons. So, you can use Two-Weapon Fighting with something else in the other hand.

Squatting Dog, Sneaky Bastard [STYLE]
You squat on the ground until your opponent comes over to hit you, then kick 'em real hard.
Prerequisite: Martial Arts Proficiency, Improved Martial Arts, Weapon Focus (unarmed strike), Absolute Bastard
Benefit: If attacked while prone, you may immediately move to standing and make a free attack with a +2 bonus to damage against your attacker.
