Noobie question

What should lv 63 rb arien should wear? (not CS set cuz i already have great cs set)

Whatever you want. o__o

L Drake?

Depends on your build. If you plan on investing points in Mana Regen then you can get by without LDrake. If not, you must get the set. The ability to spam skills far outweighs the extra damage you get from higher level sets if all you do is stage.

If you plan on moving onto Myth, you will need LDrake whether you have Mana Regen or not.
