Skill Focus (3.5)

SKILL FOCUS [General]
Select one skill which you have four ranks in.

Prerequisite: Selected skill 4 ranks.

Benefit: You gain a +4 bonus to skill checks made with the selected skill and you can take 10 with the skill even if you normally would not be able to (such as Knowledge checks or using skills during combat).

Special: This feat can be taken multiple times; its effects do not stack. Each time it is selected it applies to a new skill.

Comments
The original Skill Focus feat sucks. Everyone knows this. In fact, most skill-based feats suck. Yet, many players out there find they enjoy playing skill-based characters and need feat boosts. This variant of Skill Focus grants a more useful skill boost.
