Divine Keystone
You magically remove and consecrate the cornerstone of a building or ruin in the center of a settlement before returning the stone to its structure to spread its divine protection into the settlement around it. Once the final hammer strike returns the stone to its structure, the area protected by the sanctified stone becomes a sacred space, protecting the living from undead. Within the protected area, the consecrated site is holy, undead creatures can't be created or raised, and living creatures are Invisible to the undead.
A successful Dispel Magic used on a specific effect removes only that effect (such as the invisibility effect). However, destroying or removing the keystone ends the entire ritual and all its effects.
Critical Success You create the effects described above, and the keystone's consecration effect doubles its radius.

Traits
A consecration spell enhances an area for an extended period of time. A given area can have only a single consecration effect at a time. The new effect attempts to counteract any existing one in areas of overlap.
Effects with the holy trait are tied to powerful magical forces of benevolence and virtue. They often have stronger effects on unholy creatures. Creatures with this trait are strongly devoted to holy causes and often have weakness to unholy. If a creature with weakness to holy uses a holy item or effect, it takes damage from its weakness.
