I think you haven't understood the question.
Here's the image:
item_id, skill, level columns are ok. But how can I know the attribute number? If I add 957883262 (like on the screen) and add skill id (3185) and level (10) I get my weapon with skill, but when I click on the weapon once it writes only +M.atk, P.atk, evasion and etc. There is no text saying that weapon has skill that I've added. So how can I know the skills attributes?
