Your Strength, Constitution, and Wisdom scores increase by 1.

Your connection to the elemental planes allows you to attune to one of the elements. When you finish a long rest, choose a damage type from acid, cold, fire, lightning or thunder. You gain resistance to this damage type until you change it again.

Due to your attunement, you can be detected by the detect magic spell. You have an aura of evocation and transmutation.

Starting at 3rd level, as a bonus action on your turn, you may shift into your wolf form for one minute. While in this shape, you cannot use any weapons, wear armor, or use equipment. You choose if your equipment merges into your new form, remains worn by you, or falls to the ground. You gain the following properties while shapeshifted:

Your claws in your hybrid form are infused with elemental energy. They deal extra damage of your Elemental Attunement type equal to 1d4 - the number of days you have been attuned to the element (minimum of 1 extra damage). 

The base extra damage increases to 2d4 at 5th level, 3d4 at 11th level, and 4d4 at 17th level.

Just like a wolf, your nose is much better than a human's. You have advantage on Wisdom (Perception) checks that rely on smell.

You have proficiency in the Survival skill.

You can communicate simple ideas with wolves, dire wolves, and wargs.

Your nature as a werewolf gives you a weakness to silver. You are considered vulnerable to damage dealt by silvered weapons and cannot carry silver coins or objects yourself. If you silver a weapon, the silver must be on the very edge and nowhere else.

Your eyes are adapted to darkness. 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.

You can speak, read, and write Common and Primordial.
