Wizard is effective for corraling Defenders and Blasters by delivering well-placed spells to the Overseers. Priest is an effective fighter here, especially because their wands can pierce through the outer walls of the cube system. Preferred healer is Necromancer running Soul Siphon, as the extra bulk makes up for the lesser damage, managing to still grant a full heal to the entire nearby party. You cannot be teleported to while cloaked, but keep your finger on the Nexus key. A mistiming will spell the Rogue’s immediate death, though. Rogue can get quick cloaked damage onto it, sneaking behind since its bullets are focused. Assassins can also throw poisons from a long distance to prevent themselves from going into any true danger while still qualifying for loot. Assassins and Mystics punch massive holes in the bulwark for other classes to rush in and damage the Cube God.
