Elemental Master (Cold)

When you gain this feat, you have become a Master of Cold. You gain the following benefits

• Spells you cast or abilities you have that deal cold damage ignore resistance. In addition, when you roll damage for a spell or feature that deals Cold damage, you can re-roll any 1's and 2's rolled, but you must take the new value
• You gain immunity to Cold damage

Additionally, as an action, you can shoot a row of Ice-spikes in a 15ft line in front of you, forcing any creatures caught by it to make a DC 14 Dexterity saving throw, taking 2d8 cold and 2d6 piercing damage and have their movement reduced by 10 feet on a failed save, and only taking half damage on a successful one.
