Once per long rest you can heal yourself a amount equal to your hit dice per level.

Example: 12 level fighter heals 12d10 hit points

Multi-class Rules: You heal with the hit dice of both classes equal to the levels in those classes so a 2nd level fighter and 10th level wizard would be healed by 2d10+10d6 hit points.

Your Strength score increases by 2, and your Constitution score increases by 1.

You have a resistance to cold. You’re also naturally adapted to cold climates, as described in chapter 5 of the Dungeon Master’s Guide.

Nordic humans grow to full size much quicker than normal humans reaching full size at around 14 to 16 years old and they live significantly longer than normal humans reaching around 150 years old before kicking the bucket although some in rare cases even out live half elves reaching over 200 years old. Nords unlike normal humans do not deteriorate with age, so while they do appear to get older they remain in physically in their prime till death.

I covered this in the main description so figure it out yourself.

Nords are humans just bigger and stronger than normal ranging from 6 to 7 feet tall and weighing in at 250 to 400 pounds. Your size is Medium. Even the smallest of nordic women can tangle with a half orc man so have fun with that.

Your base walking speed is 30 feet.

You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

You can speak, read, and write Common, Giant, and one language of your choosing.
