Weapon Focus
Prerequisites: +2 CA, proficient with selected weapon
Cost: 4 General Upgrade Points
Weapon Focus gives a +1 bonus to all attacks made with the selected weapon. You may not choose a type of ammunition for Weapon Focus, though thrown weapons are acceptable. A different feat is not required for weapons which are both melee and ranged - the bonus applies either way it is used.
Special rules are as follows:
Weapon Focus (Unarmed Strike) requires either Brawler or Unarmed Strike. If the character has Unarmed Strike, the bonus applies to both lethal and sublethal damage.
Weapon Focus (Grapple) requires Improved Grapple and gives bonuses only to the following actions, as listed on the Grapple page. Attack Opponent gets the +1, as does the grapple check for the Crush action. Use Opponent's Weapon receives the bonus to both the grapple check and resulting attack roll, regardless of the weapon - the bonus also applies to grapple checks made to resist this action.
Weapon Focus (Touch Attack) applies to all touch attacks and is helpful in starting trips, grabs, etc., in addition to a number of other uses. This does not cover Ranged Touch Attacks, for which this feat can be taken separately.
Theoretically the weapon chosen can be anything you can dream up (using arrows in melee), but anything strange will require an exotic proficiency, as the character must be proficient (see prerequisites). Keep in mind that any special attacks not specifically mentioned (trip, grab, etc.) cannot be the subject of Weapon Focus.
Weapon Focus (Shield Bash) applies only to one category of shield. For example, one must choose Weapon Focus (Light Shield) or (Simple Shield). The option also exists to choose a single shield, for example (buckler), which applies to both shield bashes and Shield Checks vs incoming projectiles, but this will not stack with the bonus provided from weapon focus in a category of shields.
If a weapon specifically mentions that it allows trip attempts, such as a Whip, the +1 applies to trip attempts as well.
Normally: You gain no such bonus.
