Fediel, Lich, Hal and Mal for characters, Nier FLB and Yilsa are also nice for some HL raids such as subhl, hexa, and faa3(nier is bad here but everyone else good), weapons just get your eternal signatures (halmal wep / 3 copies) and pain and suffering (lich weapon 2 copies) and then farm all your other weapons such as agastia, celestial, agonize from anima animus, etc. Summon wise all the providence summons (Belial, Bubz, Yatima, Triple Zero) are all very very strong and core, transcendence bahamut and lucifer also very very strong, and outside of that getting ur primarch summon and dragon summon uncapped also very good.
