Shield of the archons

Shield of the archons was a planar spell used by priests as a means of protection from spells.

Effects
When cast, a magical shield was created by altruistic energies. The shield spanned a 120° angle, and absorbed incoming spells sent towards the caster. Area-of-effect spells had a lower chance of affecting the shielded creature, and reduced the damage taken, if hit. However, the shield had a chance to break, and that chance was proportional to the power of the spell cast.

The magical shield would dynamically change angular coverage to absorb the most powerful spell, provided several spells were directed at the shielded creature at the same time.

Components
The powerful spell only required a verbal component.

History
Shield of the archons was created by priests that worked alongside celestial archons of the Seven Heavens. Thus, such a spell was used by good-aligned priests who associated with these archons, but other than that, was very rare.
