Ultimate Protection

A barrier of shimmering force encloses up to 50ft and a minimum of 5 feet within range. An unwilling creature must make a Dexterity saving throw. On a failed save, the creature is enclosed for the duration.

Nothing--not physical objects, energy, or other spell effects--can pass through the barrier unless the magic is dimensional travel in or out, though a creature in the barrier can breathe there. The barrier is immune to all damage, and a creature or object inside can't be damaged by attacks or effects originating from outside.

while inside the barrier all creatures receive healing as 4d10
