Thanks guys! Yes, Divine Intervention created a world of anomalies for us, but by making the rules function correctly for it, we have other opportunities we can add in the near future.
The Whirling Spirit was a great example.
We are working on a Blink spell for the Wizard, which enables him to temporarily teleport out of the arena, and then reappear back again a moment later. This will enable him to escape attacks or spells, and will be one of his most useful signature spells.
