Benefit: In melee, every time you miss because of concealment, you can reroll your miss chance percentile roll one time to see if you actually hit.

An invisible attacker gets no advantages related to hitting you in melee. That is, you don’t lose your Dexterity bonus to Armor Class, and the attacker doesn’t get the usual +2 bonus for being invisible. The invisible attacker’s bonuses do still apply for ranged attacks, however.

You take only half the usual penalty to speed for being unable to see. Darkness and poor visibility in general reduces your speed to three-quarters normal, instead of one-half.

Normal: Regular attack roll modifiers for invisible attackers trying to hit you apply, and you lose your Dexterity bonus to AC. The speed reduction for darkness and poor visibility also applies.

Normal: Regular attack roll modifiers for invisible opponents apply, as do speed reduction penalties for darkness and low visibility.

Special: The Blind Shot feat is of no use against a character who is subject to a Blink spell.

Benefit: When you use the attack action or the full attack action in melee, you can take a penalty of as much as –5 on your attack roll and add the same number (+5 or less) as a dodge bonus to your Armor Class. This number may not exceed your base attack bonus. The changes to attack rolls and Armor Class last until your next action.

Normal: A character without the Combat Expertise feat can fight defensively while using the attack or full attack action to take a –4 penalty on attack rolls and gain a +2 dodge bonus to Armor Class.

Special: A rogue with the Combat Reflexes feat still can only make one attack of opportunity in a round if he uses his opportunist ability to make that attack.

Benefit: You must have at least one hand free (holding nothing) to use this feat. Once per round when you would normally be hit with a ranged weapon, you may deflect it so that you take no damage from it. You must be aware of the attack and not flatfooted.

Attempting to deflect a ranged weapon doesn’t count as an action. Unusually massive ranged weapons and ranged attacks generated by spell effects can’t be deflected.

Special: A monk may select Deflect Arrows as a bonus feat at 2nd level, even if she does not meet the prerequisites.

Special: The character can gain this feat multiple times. Its effects do not stack. Each time the character takes the feat, it applies to a different bonus.

Special: The character can gain this feat multiple times. Each time The character takes the feat, it applies to a new weapon. Proficiency with the bastard sword or the Dwarven waraxe has a prerequisite of Str 13+.

Special: An 11th-level ranger who has chosen the two-weapon combat style is treated as having Greater Two-Weapon Fighting, even if he does not have the prerequisites for it, but only when he is wearing light or no armor.

Benefit: You gain a +1 bonus on all attack rolls you make using the selected weapon. This bonus stacks with other bonuses on attack rolls, including the one from Weapon Focus (see below).

Special: You can gain Greater Weapon Focus multiple times. Its effects do not stack. Each time you take the feat, it applies to a new type of weapon.

A fighter must have Greater Weapon Focus with a given weapon to gain the Greater Weapon Specialization feat for that weapon.

Benefit: You gain a +2 bonus on all damage rolls you make using the selected weapon. This bonus stacks with other bonuses on damage rolls, including the one from Weapon Specialization.

Special: You can gain Greater Weapon Specialization multiple times. Its effects do not stack. Each time you take the feat, it applies to a new type of weapon.

Special:  DM's are encouraged to keep careful track of a character's arrows.  A high level character using this feat tends to run out of available arrows very fast.  Also, a character may only carry "so many" arrows readily available.

Normal: You must move in a straight line to perform a charge maneuver. 

Benefit: When using the weapon you selected, your threat range is doubled.

Special: You can gain Improved Critical multiple times. The effects do not stack. Each time you take the feat, it applies to a new type of weapon.

Benefit: You do not provoke an attack of opportunity when you attempt to disarm an opponent, nor does the opponent have a chance to disarm you. You also gain a +4 bonus on the opposed attack roll you make to disarm your opponent.

Normal: See the normal disarm rules.

Special: A monk may select Improved Disarm as a bonus feat at 6th level, even if she does not meet the prerequisites.

Benefit: You can make a Bluff check to feint in combat as a move action.

Normal: Feinting in combat is a standard action.

Benefit: You do not provoke an attack of opportunity when you make a touch attack to start a grapple. You also gain a +4 bonus on all grapple checks, regardless of whether you started the grapple.

Normal: Without this feat, you provoke an attack of opportunity when you make a touch attack to start a grapple.

Special: A monk may select Improved Grapple as a bonus feat at 1st level, even if she does not meet the prerequisites.

Benefit: When you attempt to overrun an opponent, the target may not choose to avoid you. You also gain a +4 bonus on your Strength check to knock down your opponent.

Benefit: Your ranged attacks ignore the AC bonus granted to targets by anything less than total cover, and the miss chance granted to targets by anything less than total concealment. Total cover and total concealment provide their normal benefits against your ranged attacks.

In addition, when you shoot or throw ranged weapons at a grappling opponent, you automatically strike at the opponent you have chosen.

Normal: See the normal rules on the effects of cover and concealment. Without this feat, a character who shoots or throws a ranged weapon at a target involved in a grapple must roll randomly to see which grappling combatant the attack strikes.

Special: An 11th-level ranger who has chosen the archery combat style is treated as having Improved Precise Shot, even if he does not have the prerequisites for it, but only when he is wearing light or no armor.

Benefit: When you perform a shield bash, you may still apply the shield’s shield bonus to your AC.

Normal: Without this feat, a character who performs a shield bash loses the shield’s shield bonus to AC until his or her next turn.

Benefit: When you strike at an object held or carried by an opponent (such as a weapon or shield), you do not provoke an attack of opportunity.

You also gain a +4 bonus on any attack roll made to attack an object held or carried by another character.

Normal: Without this feat, you provoke an attack of opportunity when you strike at an object held or carried by another character.

Benefit: You do not provoke an attack of opportunity when you attempt to trip an opponent while you are unarmed. You also gain a +4 bonus on your Strength check to trip your opponent.

If you trip an opponent in melee combat, you immediately get a melee attack against that opponent as if you hadn’t used your attack for the trip attempt.

Normal: Without this feat, you provoke an attack of opportunity when you attempt to trip an opponent while you are unarmed.

Benefit: In addition to the standard single extra attack you get with an off-hand weapon, you get a second attack with it, albeit at a –5 penalty.

Normal: Without this feat, you can only get a single extra attack with an off-hand weapon.

Special: A 6th-level ranger who has chosen the two-weapon combat style is treated as having Improved Two-Weapon Fighting, even if he does not have the prerequisites for it, but only when he is wearing light or no armor.

Benefit: You are considered to be armed even when unarmed —that is, you do not provoke attacks or opportunity from armed opponents when you attack them while unarmed. However, you still get an attack of opportunity against any opponent who makes an unarmed attack on you.

In addition, your unarmed strikes can deal lethal or nonlethal damage, at your option.

Normal: Without this feat, you are considered unarmed when attacking with an unarmed strike, and you can deal only nonlethal damage with such an attack.

Benefit: As a standard action, you may fire two arrows at a single opponent within 30 feet. Both arrows use the same attack roll (with a –4 penalty) to determine success and deal damage normally (but see Special).

For every five points of base attack bonus you have above +6, you may add one additional arrow to this attack, to a maximum of four arrows at a base attack bonus of +16. However, each arrow after the second adds a cumulative –2 penalty on the attack roll (for a total penalty of –6 for three arrows and –8 for four).

Damage reduction and other resistances apply separately against each arrow fired.

Special: Regardless of the number of arrows you fire, you apply precision-based damage only once. If you score a critical hit, only the first arrow fired deals critical damage; all others deal regular damage.

A 6th-level ranger who has chosen the archery combat style is treated as having Manyshot even if he does not have the prerequisites for it, but only when he is wearing light or no armor.

Note: A condition that makes the character lose the Dexterity bonus to Armor Class (if any) also makes the character lose dodge bonuses. Also, dodge bonuses stack with each other, unlike most types of bonuses.

Benefit: On your action, before making attack rolls for a round, you may choose to subtract a number from all melee attack rolls and add the same number to all melee damage rolls. This number may not exceed your base attack bonus. The penalty on attacks and bonus on damage apply until your next turn.

Special: If you are attacking with a two-handed weapon, or with a one-handed weapon wielded in two hands, instead add three times your strength modifier to the damage roll.  You can’t add the bonus from Power Charge to the damage dealt with a light weapon (except with unarmed strikes or natural weapon attacks).

Normal:  A charge action does not grant any additional damage.

Special: You can take this feat multiple times.  Each time you do, it applies to a new kind of weapon.  You may use this ability only once per day per kind of weapon to which it applies.

Benefit: The time required for you to reload your chosen type of crossbow is reduced to a free action (for a hand or light crossbow) or a move action (for a heavy crossbow). Reloading a crossbow still provokes an attack of opportunity.

If you have selected this feat for hand crossbow or light crossbow, you may fire that weapon as many times in a full attack action as you could attack if you were using a bow.

Normal: A character without this feat needs a move action to reload a hand or light crossbow, or a full-round action to reload a heavy crossbow.

Benefit: You can get one extra attack per round with a ranged weapon. The attack is at your highest base attack bonus, but each attack you make in that round (the extra one and the normal ones) takes a –2 penalty. You must use the full attack action to use this feat.

Special: A 2nd-level ranger who has chosen the archery combat style is treated as having Rapid Shot, even if he does not have the prerequisites for it, but only when he is wearing light or no armor.

Normal: Cover normally gives a +4 bonus to AC.

Benefit: When using the Deflect Arrows feat you may catch the weapon instead of just deflecting it. Thrown weapons can immediately be thrown back at the original attacker (even though it isn’t your turn) or kept for later use.  You must have at least one hand free (holding nothing) to use this feat.

Normal: When making a melee attack, you get a +2 flanking bonus if your opponent is threatened by a character or creature friendly to you on the opponent’s opposite border or opposite corner.

Benefit: You must declare that you are using this feat before you make your attack roll (thus, a failed attack roll ruins the attempt). Stunning Fist forces a foe damaged by your unarmed attack to make a Fortitude saving throw (DC 10 + 1/2 your character level + your Wis modifier), in addition to dealing damage normally. A defender who fails this saving throw is stunned for 1 round (until just before your next action). A stunned character can’t act, loses any Dexterity bonus to AC, and takes a –2 penalty to AC. You may attempt a stunning attack once per day for every four levels you have attained (but see Special), and no more than once per round. Constructs, oozes, plants, undead, incorporeal creatures, and creatures immune to critical hits cannot be stunned.

Special: A monk may select Stunning Fist as a bonus feat at 1st level, even if she does not meet the prerequisites. A monk who selects this feat may attempt a stunning attack a number of times per day equal to her monk level, plus one more time per day for every four levels she has in classes other than monk.

Benefit: When wielding a double weapon or two weapons (not including natural weapons or unarmed strikes), you gain a +1 shield bonus to your AC.

Benefit: Your penalties on attack rolls for fighting with two weapons are reduced. The penalty for your primary hand lessens by 2 and the one for your off hand lessens by 6.

Normal: If you wield a second weapon in your off hand, you can get one extra attack per round with that weapon. When fighting in this way you suffer a –6 penalty with your regular attack or attacks with your primary hand and a –10 penalty to the attack with your off hand. If your off-hand weapon is light the penalties are reduced by 2 each. (An unarmed strike is always considered light.)

Normal:  See Strike a Weapon page 136 of the Players Handbook.

Benefit: You gain a +1 bonus on all attack rolls you make using the selected weapon.

Special: You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a new type of weapon.

Special:  You cannot gain this feat multiple times.  The time required to attain and maintain this level of skill doesn't allow a character to be grand master of more than one weapon.

Special:  You cannot gain this feat multiple times.  The time required to attain and maintain this level of skill doesn't allow a character to be master of more than one weapon.

Benefit: The character adds +2 to all damage inflicted with the weapon the character has specialized with. If the weapon is a ranged weapon, the target must be within 30 feet.

Special: The character can gain this feat multiple times. Its effects do not stack. Each time the character takes the feat, it applies to a new weapon. A fighter may choose this feat as a bonus feat.

Benefit: When you use the full attack action, you can give up your regular attacks and instead make one melee attack at your full base attack bonus against each opponent within reach.

When you use the Whirlwind Attack feat, you also forfeit any bonus or extra attacks granted by other feats, spells, or abilities.
