Your attacks 1d6 deal extra Precision damage anytime your target has a Defense Penalty Status Affect, or when you’re flanking a target. Should you score a critical hit with a sneak attack, this extra damage is not multiplied. You must attack the target with a melee weapon to Sneak Attack.

If the character Sneak Attacks with a Light Melee Weapon the damage is increased to a us d8's. In the opposite, if a character Sneak Attacks with a Two-Handed weapon the damage is reduced to d4's.

You may Sneak Attack multiple times, but for every attack following the first, you must spend 2 TP to do so. Furthermore, the cost increases by 2 TP for every subsequent attack. For example, if you successfully attack a creature three times, and wish to apply Sneak Attack on each hit, you must spend a total of 6 TP - the first attack costs none, the second attack costs two, and the third attack costs four (and so on).

With a weapon that deals nonlethal damage (like a sap, whip, or an unarmed strike), you can instead make a sneak attack that deals nonlethal damage instead of lethal damage. A character cannot use a weapon that deals lethal damage to deal nonlethal damage in a sneak attack, not even with the usual –4 penalty.

Lesser Sneak Attack

The character must be able to see the target well enough to pick out a vital spot and must be able to reach such a spot. Additionally, you cannot sneak attack while striking a creature with concealment.

You add a number of sneak attack dice equal to your BaB. (If Larry has a 3 BaB, he would add 3d6 if he Sneak Attacks with his Longsword.)

All damage from Sneak Attack is treated as an Enhancement Bonus, meaning it does not stack with other Enhancement bonuses and you must select which one is applied. (Some Enhancement bonuses include but are not limited to: Enchanted weapon damage, Spellstrike, Rage, Masterwork weapon (Damage))
