I get all A's on my report cards so I guess that 8 intelligence is well deserved.
Remember that 10 STR is suppose to be a body builder.
So 10 in INT would mean very very very very very very smart.
Like Nasa scientist smart, prodigy smart.
So 8 would mean like: extremely smart.
On that note I have to drop my PER to 7 since my tongue is very bad when it comes to tasting stuff, things too sweet or too spicy for others are mellow to me.
