Making Autocast SC/AC what gears should i get and aim for?

hi everyone, havent played ragnarok in a long time and its actually my first time in IRO. i decided to make an autocast SC/AB and ive recently just become a shadow chaser and reached lvl 100. I however have no idea what gear i should be using at my current level and what i should be aiming for in the future. I would very much love some advice, please and thank you!
