Chilling Gaze

You look at a creature within range with a terrifying gaze that sends a chill down their spine.

The creature must make a Wisdom saving throw. On fail: the target takes 3d6 cold damage, and must roll a d6. On a roll of 2-4, the target takes an additional 1d8 cold damage, and will have its movement speed halved on its following turn. On a roll of 1, the target is enveloped in frost, takes an additional 2d8 cold damage, and cannot move or take any action requiring somatic components on its following turn.

When casted at 4th level or above: the target takes an additional 1d6 initial cold damage per added level. Additionally, if the rolled d6's result is 1, the target is frightened for a number of turns equal to the caster's charisma modifier (cannot go below 1).
