Become Moonshadow

As with most transformation spells, all of your held items and worn equipment are transformed with you, and grant you no benefit while you’re transformed.

Cantrip

This turns you into a living shadow. You can move a number of zones equal to your Magic Power. As a shadow, physical obstacles are no hassle, and you will have no problem moving though rough terrain. The only consideration is amount of light. Zones that are unlit cost 1 point of movement to go through (up to a full moon on a cloudless night), ones with candle or torchlight cost 2, and bright daylight costs 3. The effect ends as soon as you’re done moving, but you can bypass any hazards along the way. While in shadow form, you have advantage on all Stealth rolls and may use your Magic Power as your assistance bonus. This effect is temporary, and at the end of your turn it ends.

Great

This acts as the cantrip version, but you can now incorporate it into another action to get extra movement. Or you can remain in shadow form as long as you concentrate. You may also lurk in a willing ally or object’s shadow and follow them wherever you see fit without ever requiring a roll other than concentration. If you are hit with fire or another intense source of light, you take double damage and are returned to your normal form.

Superior

This acts as the Great version, but now you can take on a 3-dimensional form to take normal actions. Every time you do so, until your next action, you take half damage from all attacks instead of no damage as you would in 2-dimensional form. Fire and other illuminated attacks damage you as normal instead of double as in 2-dimensional form.

Ultimate

This acts as the Superior version, but the effect lasts until sunrise or noon, whichever is sooner. If you are forced out of shadow form, you can reenter it on your next turn.
