Bind Guardian

This spell is used to bind a guardian spirit to a new site or to a physical object. The spirit gets a saving throw vs. spell to resist. A successful save means the spirit remains free and can attack the shaman. If the spirit is currently guarding a particular place, the shaman can bind it into a bone (which must be at least as old as the spirit – tricky if the spirit has been there for several centuries). As long as the shaman carries that bone, the guardian spirit con be called once per week to defend the shaman for up to a turn. The guardian will not otherwise obey any commands. Only the casting shaman can use the bone in this way.

The spell can also be used to reset the spirit – taking it from the bone and placing it as a guard over a new site specified by the caster. The new location can be no more than one hundred yards across, and must be a fixed, static area with clear boundaries. Movable objects like tents and chariots cannot have guardian spirits set over them. In open areas, a boundary must be defined with a fence, ditches, or something similar. If the new site has no clear perimeter, or if the boundary is destroyed, the spirit guards only an area 15 feet across in the very center.

When the spirit is removed from the bone to be set at a new site, the bone crumbles away.
