Rime's binding ice

SM, self (30ft. cone), instantaneous
A burst of cold energy emanates from you in a
30ft. cone. Each creature in that area must make
a Constitution saving throw. On a failed save, a creature takes 3d8 cold damage and is hindered
by ice for 1 minute, or until it or another creature
within reach of it uses an action to break away the
ice. A creature hindered by ice has its speed
reduced to 0. On a successful save, a creature
takes half as much damage and isn't hindered.
