You can solo him with the epic Lady Annabelle on normal and hard all floors, if you don't have her master butcher/vogoth teams work. As this is normal doom tower you can bring a couple of revivers and get through it. Looking at your roster above you can use Skytouched to place revive on death on everyone before the big bombs go off. Scyl, Kaiden, Uugo, Hoforeez are revive options, you only really need Geomancer as dps the rest can be support/revivers. Ninja placing HP burn as well is hindering you as Geomancer specifically needs HIS hp burn to be on the boss to proc his passive.
