Eden

If you have your Vengeful CS Set and Glorious Dragon Cloak (or any other of course) you might want to get to farm the upgraded versions,

which can be obtained in Eden with the recipes from the exchanger at the start of the area.

If you have every quest item you need to get, try to get started with the Alchemy system,

so you can create the set for yourself, or just ask one of your friends, who already has the needed Alchemy Level for the creation.
