Your blood runs cold, your instincts sharpen, and your body adapts to merciless environments.

• You gain resistance to cold damage. In addition, you are immune to the effects of extreme cold, as described in chapter 5 of the Dungeon Master’s Guide.

• Arctic Scales: When you deal damage to a creature that is grappled by you, restrained by you, or knocked prone by you, you deal additional cold damage equal to your proficiency bonus. If the creature is already suffering from the effects of extreme cold or magical cold terrain (such as sleet storm or ice storm), this additional damage is doubled.
