Tartarus is an option, but if you already have waterworks, its honestly not worth the grind. I'd recommend just holding out till 100 to get darkmoore gear.
Tartarus is optional but the wands that it drop are really good in pierce, and the tartarus gear gives pretty good critical. I personally would say its worth grinding Tartarus just for the wand. The gear is optional.
- Tartarus hat or Azteca crafted hat. Then the Khrysalis crafted hat at 96+
Robe:
- Tartarus Robe
Boots:
- Proffessor's Hoard pack boots of your school
Wand:
- Proffessor's Hoard Pack wand of your school
Athame:
- Blade of the Felled Titan
Amulet:
- Amulet of Divine Influence is the best but it is not worth the grind at all. I would use the Horizon of Underworld Charm, as it grants the most health.
Ring:
- Alpha and Omega Ring
Deck: Your schools deck that grants health, and eventually the pip deck at 95+
