A creature hindered by ice has its speed reduced to 0.

Level 10: Frostfell Curse

You gain the ability to cast Chilling Hex once per short rest.

Chilling Invocation: Choose one eldritch invocation that modifies a cantrip that you know. You can now modify any cantrip that deals cold damage naturally through the cantrip or through your Touch by Frost ability in the same way.

Chilling Hex: You hex a target with a bonus action. The hexed target takes 2d8 cold damage whenever you deal damage to it. The hexed target also emits a chilling aura, creating a 15-foot emanation around itself that reduces the movement speed of targets of your choice in the area by 10 feet. If your hexed target is killed while you have Armor of Agathys active, it restores up to 10 temporary hit points to your Armor of Agathys hit point pool, not exceeding the total hit points of the current spell. The hex can be moved to another target as a free action if the current target is killed or as a bonus action to move from a living target to another living target.
