Hi, welcome to Grand Chase Wiki! Thanks for your edit to the File:180px-Inspector Gadget s Dr Claw by mis.jpg page. Be sure to read the Manual of Style and familiarize yourself with some common Wiki markup and to see what is expected when adding content.
Excuse me, I know you were trying to edit Jin, Rufus, Zero, and Asin's "weaknesses" there, but what you were trying there is very inaccurate to what's on based on their background profile on NAVER blog.
So please try to read on what's the actual source of the character's background story instead of making things up.
