You channel the incredibly cold power of the cosmos and unleash a wave of frigid energy that freezes everything in its path. You and all creatures within a 30-foot radius centered on you take on a faint blue hue and are immune to cold damage for the spell's duration.

At the end of each of your turns, all creatures within the radius take 10d10 cold damage, or half damage on a successful Constitution saving throw. In addition, any water-based creatures that fail their save are also restrained until the end of their next turn as the water in their bodies begins to freeze.

Furthermore, any nonmagical objects that are completely within the area of effect take on a fragile, crackling appearance, and become exceedingly brittle until the spell ends. Any fragile object struck by an attack or takes any amount of damage shatters and becomes useless.
