Conjure Spell Prism

You materialize up to 4 floating crystal prisms in an empty space you can see within range. Whenever a spell with a ranged attack directly hits the prism, that spell is absorbed by the prism, then redirected as a beam attack in the direction the prism is facing. Creatures caught in the path of the beam are subject to the saving throws, damage, and magical effects of being hit by the standard form of that spell. Spells reflected through the prism change their area of effect to a line and lose any additional targeting properties such as splash damage, moving to new targets, or homing capabilities. The beam is 5 feet wide and its reach is equal to the available distance that the original spell can still travel. A beam can reflect off of multiple prisms if the cast spell has available range to do so.

The angle of the crystal prism is determined by the caster when it is conjured. The caster may use a bonus action to adjust the angle their prisms are facing, but cannot adjust where they are positioned. The prism has an AC of 10 and Total Hit Points equal to the caster's Spell Save DC + Spell Modifier Bonus. It is resistant to piercing damage, but weak to sonic damage. A prism will not reflect touch spells or indirect spell effects. Each prism can reflect a number of spells equal to the spell level it was summoned at before it shatters.
