Arcane Barrier

When you cast this spell, you create a shimmering barrier of magical energy that surrounds you. The barrier has a radius of 10 feet and follows you as you move. The barrier provides cover to all creatures within its radius, granting them a +2 bonus to AC and Dexterity saving throws. In addition, the barrier absorbs the first 10 points of damage from any attack that would hit a creature within its radius. Once the barrier has absorbed 10 points of damage, it dissipates.

This spell is useful for protecting yourself and your allies in combat, as the barrier can absorb some of the damage from incoming attacks and provide cover against ranged attacks. The barrier's radius is also large enough to cover multiple allies, making it a great defensive option for a group of adventurers. Additionally, the spell's ability to absorb more damage at higher levels makes it a versatile option that can scale with the challenges faced by the party.
