Incarnate the Last of Lacers

Grasping Ice

1-level Evocation

The next time you hit a creature with an elemental attack before this form ends, a burst of water latches onto the creature's feet and freezes, holding them to the ground. The target must succeed on a Strength saving throw or be restrained by the ice until the form ends. If the target succeeds on the save, they destroy the ice and break free. While restrained by this form, the target takes 1d6 cold damage at the start of each of its turns. A creature restrained by your ice or one that can touch the creature can use its action to make a Strength check against your ki save DC. On a success, the target is freed.
 
At higher levels: the damage increases by 1d6 for each level above 1st.
