3 Shadow Killer (equipped with the best attack gems +30 +15 +15) + 1 Juliet (equipped with best health gem +500) and 1 Devourer (equipped with +350 health, +40 speed and +10 attack gems) This build sometimes reach past level 30 depending on how weak your enemies is or how long your Queen Juliet last before she stops healing the party when her health reaches the yellow zone.
