Backstab Ex: Thugs are not as subtle or skilled as rogues, but they still know that the fastest way to a man's heart is through their ribcage. A thug may perform a backstab against an opponent who does not get his Dexterity bonus to AC. This does not include flanked opponents and may not be performed at range. A backstab deals an additional 1d4 points of damage, increasing 1d4 at 5th level and every 5 levels thereafter. All the limits of sneak attacks apply to the backstab ability.

Combat Feat: Thugs lead rough lives. At level 10 a thug may pick one feat from a fighter's list of bonus feats except for weapon specialization. A second feat may be chosen at 20th level.

Special Ability: A thug may choose crippling strike, defensive roll or opportunist from the rogue's list of special abilities.
