Form of Ice

You freeze over, taking on a form of elemental ice. Until the spell ends, you gain the following benefits:

• You are immune to cold damage.

• You can move across difficult terrain created by ice or snow without spending extra movement.

• The ground in a 15-foot radius around you is icy and is difficult terrain for creatures other than you. The radius moves with you.

• You can use your action to create a 30-foot cone of freezing wind extending from your outstretched hand in a direction you choose. Each creature in the cone must make a Constitution saving throw. A creature takes 4d8 cold damage on a failed save, or half as much damage on a successful one. A creature that fails its save against this effect has its speed halved until the start of your next turn.

• During your turn, if you roll cold damage, you gain temporary hit points equal to one die rolled (your choice).
