Erden's Ultimate Cone of Cold

Harmless ice spikes form on the caster's arms as a blast of cold air erupts from their hands. Each creature in a 120-foot cone must make a Constitution saving throw, DC 20. Any creatures caught in the blast take 10d10 cold damage on a failed save, or half as much damage on a successful one. On a failed save the affected creature is frozen for a round and takes double damage if attacked, though this shatters the ice around them.

After the spell is cast snowflakes begin to fall from the sky. A creature killed by this spell becomes a frozen statue which then shatters into a fine snow that then floats away into the breeze.
