Freeze Wave

3-point evocation (cold)
Casting time:	action
Range:	self (20-foot cone)
Components:	V, S
Duration:	concentration, up to 1 minute

With a stomp of your foot into the ground (no free hand required for this somatic component), you conjure a wave of ice that races through a 20-foot cone originating from you. Ground in this area becomes difficult terrain for creatures other than you while the spell persists.
 Any creature in the area when you cast this spell takes 2d4 cold damage, and must succeed on a Strength saving throw or become restrained by the ice freezing it in place. A creature restrained by this spell can repeat this save after each action it takes, and on a success breaks free from the ice to end the effect on itself.
 When this spell ends (even outside of your turn), the ice violently shatters apart as it sublimates into the air. Each creature other than you in the area takes 2d4 slashing damage.
 Upcast. You can upcast this spell by expending extra spell points when you cast it. For each extra point, increase the cone's size by 10 feet.
