Weapon Focus
Type: General
Source: Player's Handbook v.3.5
Choose one type of weapon, such as greataxe. You are especially good at using this weapon. You can choose "unarmed strike" or "grapple" for your weapon for purposes of this feat. If you are a spellcaster, you can choose "ray," in which case you are especially good with rays, such as the one produced by the ray of frost spell.
Prerequisite: Proficient with weapon, base attack bonus +1 or higher
Benefit: You add +1 to 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 weapon. A fighter must have Weapon Focus with a weapon to gain the Weapon Specialization feat for that weapon.
For Spell casters: Choose one category of weapon-like spell (ray, energy missile, or touch spell). You add +1 to all attack rolls made with such spells. You can gain this feat multiple times, choosing a different weapon or category of weapon-like spell each time.
