You weave a mutable form of elemental energy, creating a shimmering barrier of force that negates any incoming –or outgoing–elemental energy.

Any elemental energy or force attempting to target the creature and any elemental energy/force being used by the creature are negated, as an antimagic field. For this purpose, “elemental energy or forces” that are negated by the shield includes:

• Spells and effects with the air, acid, earth, cold, electricity, fire, or water descriptor, aside from the prism shield itself.
• Magical or supernatural effects that deal acid, cold, electricity, or fire damage, including magic items that deal these damage types (like a flaming weapon)
• Contact by summoned creatures with the elemental, air, earth, cold, fire, or water subtypes. This prevents such summoned creatures from harming the creature directly, though indirect forms of contact (such as throwing a weapon at them) can still harm the target. A summoned creature with spell resistance can possibly still hit the target, as described in the antimagic field spell.

Artifacts and deities are unaffected by this spell’s effects. Any effects that can negate, penetrate, or otherwise interact with an antimagic field has the same effect on the prism shield.

If you sacrifice a prepared prism shield spell to create a spell twist, you treat the spell twist as if created using a spell one level lower than normal (minimum 1st level) but you gain a +5 bonus on checks to overcome spell resistance with that twist, similar to the effects of a Piercing Spell metamagic feat.
