Which level 7 creature is the best, and why?

The strongest ones are definitely the Archangels. One-on-one, a Black Dragon might defeat him, but the Archangel can be strengthened with magic. Enemy spells don't affect the Black Dragon – that's good. But you can't cast friendly spells either... Resurrection again...
No, the Archangel still burns (sorry for the sacrilege) with a hellish flamethrower. :smile16:
