Darkvision. Thanks to your infernal heritage, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.
Cold Resistance. You have an innate connection to the freezing peaks of Vuralx's domain. You have resistance to cold damage.
Breath of the Mountain. You are naturally acclimated to high altitudes, including elevations above 20,000ft.
Legacy of Ilkaeras. Channelling the might of howling gales and frigid temperatures is second nature to you. You know the Gust cantrip. When you reach 3rd level, you can cast the Armour of Agathys spell as a 2nd-level spell once with this trait and regain the ability to do so when you finish a long rest. When you reach 5th level, you can cast the Warding Wind spell once with this trait and regain the ability to do so when you finish a long rest. Charisma is your spellcasting ability for these spells.
