Nimble Fingers (3.5e Trait)
From D&D Wiki
Your hands are quick and precise but you lack in upper-body strength.
Benefit: You gain a +1 bonus to sleight of hand checks.
Drawback: You take a -2 penalty on all climb checks.
Roleplaying Ideas: Creatures with this trait may have a tendency toward theft or trickery. Preferring not to have to pull themselves out of a bad situation they would rather avoid a battle altogether, taking whatever they need where they see it
