Reference: Star Wars Saga Edition Core Rulebook (86).
Prerequisites: Martial Arts I, base attack bonus +3.
Effect: Damage dealt by your unarmed attacks increases by one die step. In addition, you gain a +1 dodge bonus to your Reflex Defense (which stacks with the dodge bonus granted by the Martial Arts I feat).
Normal: The amount of damage you deal with a successful unarmed attack is based on your size: Small, 1d3; Medium, 1d4; Large, 1d6.
Special: A situation that makes you lose your Dexterity bonus to Reflex Defense (if any) also makes you lose any dodge bonuses. Also, dodge bonuses stack with each other, unlike most other types of bonuses.
