Arcane Barrier

This spell conjures an immovable, translucent wall of flickering purple and blue arcane energy. Measuring 10 feet square and 1 inch thick, the barrier must be anchored with at least one edge against a solid surface. It provides bright illumination in a 10-foot radius, followed by an additional 10 feet of dim light. Functioning as a medium-sized object for the purposes of providing cover, the barrier has an Armor Class of 14 and 20 Hit Points. It possesses total immunity to force, poison, and psychic damage.

Should the barrier be struck by Magic Missiles, the bolts are instantly reflected toward the original caster, who becomes the spell's new target.

While durable, the barrier is instantly negated by the effects of a Disintegrate or Dispel Magic spell.

At Higher Levels: For every spell slot level used above 2nd, the barrier's resilience increases, granting it an extra 10 hit points and 1 additional point of Armor Class.
