This spell absorbs all spells cast at the caster. The number of spell levels affected is equal to half the caster's level. As long as there are spell levels remaining in the shield, incoming spells will be absorbed. For example, if a 9th level spell is cast at the caster and there is only 1 spell level remaining in the shield, the spell will still be absorbed. Shield of the Archons will also absorb Spells cast from scrolls, innate spell-like abilities, Dispel Magic, area of effect spell cast directly on caster. This spell won't work on area of effect spells not centered on casters and area of effect spells that are stationary like Cloudkill or Stinking Cloud.
