Terreo Succurro (3.5e Trait)
From D&D Wiki
You need to figure things out for yourself, but you are pretty good at it.
Prerequisite: Int 15
Benefit: You gain a +2 on all Intelligence-based checks.
Drawback: When trying to find a solution to a problem, you need to solve it yourself. If somebody else makes a suggestion or tells you the solution, you will try to find your own completely different way to solve the problem. Whenever another character makes a suggestion, make a DC 20 Will save or completely disregard the statement and not settle with any solution similar to the suggestion.
