Circle of power

Circle of power was an abjuration spell for paladins that created a sphere of divine radiance centered on the caster.

Effects
The 30-foot-wide (9.1 meters) sphere gave all allies of the caster within it an advantage to resist spells cast against them. An affected ally who was able to withstand a spell and suffer only partial damage would instead take no damage from the spell.

Components
Only a vocal component was needed.
