World cutting slash

You unleash a slash that distorts space itself, cutting through all matter in a 120-foot line, 10 feet wide. Each creature in this area must make a Dexterity saving throw. On a failed save, they take 20d10 force damage, ignoring resistance and immunity. On a success, they take half damage.

• Unstoppable Force: Objects, structures, and magical barriers within the range are automatically destroyed, regardless of their durability.
• Overwhelming Pressure: Any creature with 50 hit points or fewer within 30 feet of you is stunned until the end of their next turn, overwhelmed by the sheer force of the attack.

Once you cast this spell, you must finish a long rest before using it again.
