Any stam class Vicious Ophidian is basically essential. It's from Aetherian Archive which is the easiest trial to do, even on vet.
Second a penetration set is nice to have NMG is still useful in this situation, or you could farm for Briarheart which will give you a lot of weapon damage & heal you on crits.
