You think highly of your wisdom and knowledge - that is, you and only you. The rest of the world knows that you are most often than not making things up to appear highly intelligent even though you need to untie your shoes to count to 20. Among all the nonsense though, you sometimes grasp the deep meaning of things - at least by sheer luck, that is.
Whenever you need to perform an INT based skill check, you don't roll 1d20 and apply any bonus. Instead roll 1d8:
- 1 is a critical failure (a 1 in d20 scale).
- 2-7 are all regular failures (consider it 2 but don't apply any modifier).
- 8 is a critical roll and will always succeed no matter what (consider it a 20).
No matter the outcome, you are always perfectly convinced of what you are saying and will argue back to anyone saying you're wrong.
