Adaptability (3.5e Feat)
From D&D Wiki
You're good at applying your strengths to things most people don't think are possible.
Benefit: Choose any skill, you can use the highest stat of the same type. Type would refer to what stat it would use normally. Physical skills use the first three stats, Strength, Dexterity, and Constitution, since they are physical characteristics. Mental skills use the last three stats, Intelligence, Wisdom, and Charisma, since they are mental characteristics.
- This is switching, not adding. you do not add both the benefits of two stats to one skill unless allowed to by some other means, in which case taking this feat will only allow you to switch one stat.
