Entropic shield is an abjuration spell makes it harder to hit the caster with ranged attacks.
A magical field appears around you, glowing with a chaotic blast of multicolored hues. This field deflects incoming arrows, rays, and other ranged attacks. Each ranged attack directed at you suffers a 20% miss chance (similar to the effects of concealment). This miss chance affects all ranged attacks for which the attackers make attack rolls, including arrows, magic arrows, Melf's acid arrow, ray of enfeeblement, and so forth. It does not affect other attacks that simply work at a distance, such as dragon breath.
