Sphere of Survival

Sphere of survival creates a sphere of protection against one type of element, and breathable atmosphere for all within. It is intended to be used on the Inner Planes, allowing a small group of planewalkers to enter into and operate within a hostile environment safely. As such, this spell does not function on the Prime Material or any of the Outer Planes.

At the time of casting, the priest must specify which element the sphere protects against. Everyone within the area of effect of the spell is protected as by the elemental protection spell. Additionally, the sphere provides all creatures within it with fresh air. The sphere maneuvers through all elemental material unhindered, even if the medium is solid rock.

Obviously, this spell is a great boon to inner-planar travel. Only its high level keeps it from becoming more widely used.

The material component is the holy symbol of the caster.
