Focused Training (3.5e Trait)
From D&D Wiki
Focused Training [Skill]
You trained yourself to master one skill at the cost of others.
Prerequisite: Int 13
Benefit: You add your Intelligence modifier to one skill of your choice. This stacks with the existing ability modifier, even if it is already intelligence.
Drawback: You do not add your Intelligence modifier to your skill points per level.
Normal: You do not add two ability modifiers to any skill.
Roleplaying Ideas: Characters who take this trait will most likely have very focused attitude, almost close minded, perhaps. Glumditch the gnome was the the best blacksmith in Hammerton, but knew little else.
