Fighting Style Specialization

Urban Fighting Style
Source: Dragon 256
This is a fighting style generally favoured by Rogues, it relies on speed and deceit and is interlaced with feints and special parries, with the idea of delaying the enemy while the character tries to escape. To purchase this combat style, a character must fulfill two prerequisites. First, he must have the Two Weapon Fighting Style proficiency. Second, the character must have proficiency in a sword of size M or less and a parrying weapon of size S.
If both of these requirements have been met, then the character can purchase this style for 5 Character Points(CPs). The style provides several benefits, in addition to those already gained by the two prerequisites. While using both weapons with this style the character gains a +1 bonus to his AC from one frontal melee attack per round. The character also gains a +2 bonus to all blocking attempts. If the character chooses to parry an attack (see pg. 27 of Combat & Tactics), he receives an AC bonus equal to one-half his level. Finally, the character may attempt to use feints to create an attack of opportunity against a foe.
To make a feint, a Dexterity/Balance check is required. If the check fails, then the character suffers a +2 penalty against his AC for the next attack - he has left himself exposed. If the Dexterity check succeeds, however, the feint has tricked the enemy, and the character makes an attack of opportunity in addition to his normal action for the round.
The benefits and advantages of this fighting style may be applied only if the character is fighting living opponents of at least animal intelligence or better. The bonuses depend on the character being able to read the body and movements of the foe. Undead and animated creatures do not give off such subtle clues, and mindless creatures are too stupid to fall for any tricks. If the character is disarmed in a fight, he cannot use the benefits of this package until he has both weapons.
If the character spends an additional 2 CPs on the urban fighting style, he receives a +2 bonus on all disarming and expert disarming attempts.

Wilderness Fighting Style
Source: Dragon 256
Thc wilderness is dangerous, and scouts often runs across orcs, ogre's, and even giants in their travels. The intelligent character would never attack such creatures by themselves. With help from allies, however, he can utilize this fighting style to help bring down the enemy. To purchase the Wilderness Fighting Style, the character must fulfill two prerequisites. First, he must be proficient in a melee weapon of medium to large size. Second, he must be have either the Single Weapon or Two Weapon Fighting Style proficiency.
When both prerequisites have been met, the character may purchase this style for 5 CPs. The wilderness style provides two benefits,. First, it allows the character to make one attack of opportunity per round, but only if he can strike from behind or if an ally is fighting the creature at the same time. Basically, the character leaps in, makes his attack, and then gets out of the way before he can be attacked. If conditions are right, a Thief with the Backstab ability may Backstab with his attack of opportunity. Second, the character can locate a vulnerability on a creature and strike that location for added damage. To locate a weak spot in a creature requires the character to spend a round studying the opponent without attacking. then a Wisdom/Intuition check is, made. If the check fails, the character cannot locate a weakness. If the check succeeds, the character has found a vulnerability in the creature. Hitting the vulnerable spot requires a called shot with a -4 attack penalty. If a called shot hits a vulnerable location, the attack inflicts an additional 2 points of damage. The character can point out the vulnerability to his allies who can then strike that location for the extra damage. The DM may rule that amorphous creatures (puddings, slimes, and so forth) do not have weak spots. He may also rule that extra-planar creatures do not have such weaknesses (elementals, for example).
