Bring in the weapons of mass destruction. We dislike pve solutions, so let it be pvp. Give us ways to semi-permanently destroy regions, turning them into wastelands.
Introduce two new scrolls for that - one to destroy and another to heal. Success rate is influenced by noble density on the continent. When the density is low, healing often fails and destruction succeeds, and vice versa.
Or sages make scrolls based on density. Low density gets more plague scrolls than healing.
