Elemental Circle of Protection

When this spell is used, a circle of any element (fire, cold, acid, etc.) explodes from the caster. The elemental circle is 30 feet wide in any direction from the caster. This circle can go through walls, floors, ceilings, and even solid ground. Only a Wish spell or the caster conjuring it away can make this elemental circle disappear. When the elemental circle appears, or if anyone directly hits it, they take 4 d10 damage of the element of the circle. As another action, the caster can choose three targets. Each of these three targets must make a DC 15 Dexterity saving throw, taking 3 d10 of the elemental damage on a failure, and half damage on a success. No one can pass through the elemental circle. While the caster remains inside the circle, they cannot use any weapons that are not ranged, and if they use any ranged weapons, the caster must make an additional DC 15 attack roll. On a success, the weapon makes it through the circle and does regular damage. On a failure, the weapon is destroyed by the element. Also, while inside this Elemental Circle of Protection the caster cannot be blinded, charmed, deafened, frightened, grappled, incapacitated, paralyzed, petrified, poisoned, prone, restrained, stunned, or unconscious. If the caster stays in the circle for longer than 30 minutes, they suffer one level of exhaustion when they exit the circle.
