Nova sorceress build for Best in Slot, sorry if there's a few spelling mistakes I'm doing it off the top of my head but I've run quite a few nova sorc so I'm doing it for memory from my head:
WeApon; (Your personal choice of the following):
Heart of Oak, Eschutas, The Oculus orb, Cresent Moon runewrd, . Call of the Arms (helpful in hardcore gives damage and life)
Armor: (Your personal choice for of the following):
Skulldor's Ire armor (but remember with this no teleport!) Enigma runeword armor for teleport, Glatiators Bane (if he on hardcore), Smoke Runeword (for a lot of defense and life saving, but no teleport)
Helmet; (Your personal choice of the following):
Harle with Top, cure runeword (for helping on hardcore), Filtering Flame runeword (I think that's her name!!! Good for hardcore)
Amulet necklace: (Your personal choice of the following):
Mara necklace, talrashs's Amulet (set item amulet good with other set item gives a bonus if you havec more from same talrasha set), Highlords amulet (1 skill for you and lightning resist pretty helpful on hardcore)
Belt//waste: (Your personal choice but imo some are better than some):
Tal Rasha waste/belt (if you use this waste it has a lot of potion slots and with the necklace you can get a lot of set item bonus it's really strong I think you get faster fast rate), gold wrap (magicfind, attack speed, other stats not bad), verdungeos (good for hardcore because it adds vitality and a lot)
Rings: (Your personal choice imo but you should think carefully before you pick what you pick):
Kathos rings (skills, life good for hardcore), stone of Jordan (skills, lightning, Mana, good for hardcore because Mana), nageleing (gg because it has 25% magic find and good for magic finding that's 60% for 2 of them).
Sk ills:
Max Nova and synergies
Max lightning mastery
Rest of points go into warmth and lightning storm.
Lmk if you have any questions. Again sorry if there's any small spelling errors I didn't get enough sleep last night.
