Spirit of the Wolf

4th-level transmutation

Casting Time: 1 action
Range: Self
Components: V, S, M (the fang of an aged wolf)
Duration: Concentration, up to 1 hour

You assume the form of an ethereal wolf. You gain the stats of a dire wolf and the following traits: Ethereal Form, Incorporeal Movement. Moreover, your movement speed increases by 10 ft. and you gain resistance to bludgeoning, piercing, and slashing damage from nonmagical attacks not made with silvered weapons. You retain your hit points, saving throw proficiencies, and Intelligence, Wisdom, and Charisma scores.

For the duration, you can revert to your normal form or transform into an ethereal wolf again as a bonus action.

Ethereal Form. Using your action, you can enter the Ethereal Plane. During this time you can move in any direction. If you move up or down, every foot of movement costs an extra foot. You can see and hear the plane you originated from, but everything looks gray, and you can’t see more than 60 feet away.

While on the Ethereal Plane, you can only affect and be affected by other creatures on that plane. Creatures that aren’t on the Ethereal Plane can’t perceive you and can’t interact with you, unless a special ability, spell, or power has given them the ability to do so.

You ignore all objects and effects that aren’t on the Ethereal Plane, allowing you to move through objects you perceive on the plane you originated from.

When the spells ends or you use your action to end this effect, you immediately return to the plane you originated from in the spot you currently occupy. If you occupy the same space as a solid object or creature when this happens, you are immediately moved to the nearest unoccupied space that you can occupy.

Incorporeal Movement. You can move through other creatures and objects as if they were difficult terrain. You take 1d10 force damage if you end your turn inside an object.
