I guess I'm a bit exagerrated about the "300k HP" with 1700 Power. BUT I really did it before. 210k HP with 1700 Power via Wizard
7x ED+ plus 3 for Eternal (MH, Neck, Pet)
PtL x 3 plus 1 for Eternal (Neck)
GC x 2 plus 1 for Eternal (MH)
BloodMagic Mythic with All Mana Based Set Affixes.. (SpellSword, CV, AD, CP, Satyr's, or Scroundrel)
Pet (Satyr's) with +15000 MP, 50% TMP
I use it once but never again because of its weakness when facing aggresive players.
