Builder

The character has a knack for constructing things.
Benefit: Pick two of the following skills: Craft {chemical}, Craft {electronic}, Craft {mechanical}, and Craft {structural}. The character gets a +2 bonus on all checks with those skills. If the character has 10 or more ranks in one of these chosen skills, the bonus increases to +4 for that skill.
Special: The character can select this feat twice. The second time, the character applies it to the two skills he didn’t pick originally.
