Battle Knave (Rogue/Fighter)

Battle knaves are rogues who look to fighters as exemplars of a more reliable and effective fighting style. The battle knave trades study of traps and roguish ways for expertise with deadly combat tricks. More heavily armed, and eventually more heavily armored than the run-of-the-mill rogue, the battle knave taunts and confuses his foes before delivering the deathblow. (Original Concept by Flak)

Primary Class: Rogue.

Secondary Class: Fighter.

Alignment: Any.

Hit Dice: d8.

Bonus Skills and Ranks: The battle knave may select three fighter skills to add to his class skills in addition to the normal rogue class skills. The battle knave gains a number of ranks at each level equal to 6 + Int modifier.

Weapon and Armor Proficiency: The battle knave is proficient with all simple and martial weapons, plus the hand crossbow. He is also proficient with light armor and the buckler. 

Critical Sneak (Ex): When a battle knave successfully strikes with a sneak attack, he may treat his attack as a critical threat instead. If he does, he deals no precision damage from the sneak attack ability, and must instead confirm the critical hit. He receives a –5 penalty on this attack. If he confirms the critical, he deals double damage as normal. If he was modifying his sneak attack with a rogue talent (such as Bleeding Attack), the extra effect conveyed by that talent only applies if the critical hit is confirmed. If the battle knave fails to confirm the critical, his attack still hits, but is neither a critical hit nor a sneak attack. This ability replaces trapfinding.

Rogue Talents: A battle knave may take the Combat Trick rogue talent any number of times. 

Vulnerability Sense (Ex): The battle knave notices the gaps in his opponents' guards, and strikes harder when they are most vulnerable. Beginning at 3rd level, the battle knave uses his level in place of his base attack bonus when flanking or any other time he could normally perform a sneak attack. This ability functions against creatures normally immune to sneak attack, but not against those without Intelligence scores (such as most constructs), nor those with all-around vision. This increase in his effec
