Character attributes
 

Which table within the database holds the information for attributes: Str, Sta, Int, Wis, Dex, etc?

I am looking to modify for a created character

The profile blob of the player holds this information. It's uneditable in the way you're wanting to do.

If you're referring to the creation of characters rather than an actual pre-existing character, you can check out char_create_point_allocations for their base stats upon creation.
