might need to nerf the Fallen Cleric a little by making it easier to resist them and reducing the duration of the charmed status (the one that prevents you attacking them) as 4 turns feels excessive unless you've stockpiled fireworks to keep them stunned that long, not to mention that the enemy shouldn't be able to act the moment stun wears off to make stun a little more impactful
also Secret Ingredient Mana Potions should nullify anti-magic fields
