Testers needed.

In the new version, banishing phoenixes will only require a ring of banishment and a sphere of light. A secondary quest from a witch will also appear, involving collecting monazite and finding the mask of justice to curse Dominic (reducing his stats, morale, and luck). Therefore, by the time the quests are completed, you can stop accumulating troops for the castle siege and start attacking immediately. I removed the dwarven artifacts from Dominic that grant immunity to dark magic spells.
