You use magic to mold yourself into a new form. Choose one of the options below. Until the spell ends, you can use an action to choose a different option.

Amphibian: Your body takes on aquatic adaptations. You can breathe underwater normally and gain a swimming speed equal to your base Speed. 

A barrier that glimmers with an oily rainbow hue pops into existence around you. The barrier moves with you and prevents creatures other than undead and constructs from passing or reaching through its surface. 

An invisible sphere of antimagic forms around you, moving with you and suppressing all magical effects within it. At the Narrator’s discretion, sufficiently powerful artifacts and deities may be able to ignore the sphere’s effects.

Your muscles swell with arcane power. They’re too clumsy to effectively wield weapons but certainly strong enough for a powerful punch.

You respond to an incoming attack with a magically-infused attack of your own. Make a melee spell attack against the creature that attacked you. If you hit, the creature takes 3d6 acid, cold, fire, lightning, poison, or thunder damage.

Casting Time: 1 reaction, which you take when a creature makes a melee attack against you

You throw your head back and howl like a beast, embracing your most basic impulses. Until the spell ends your hair grows, your features become more feral, and sharp claws grow on your fingers. You gain a +1 bonus to AC, your Speed increases by 10 feet, you have advantage on Perception checks, and your unarmed strikes deal 1d8 slashing damage.

With the aid of a divining tool, you receive an omen from beyond the Material Plane about the results of a specific course of action that you intend to take within the next 30 minutes. The Narrator chooses from the following: 

Until the spell ends, roll 1d20 at the end of each of your turns. When you roll an 11 or higher you disappear and reappear in the Ethereal Plane (if you are already on the Ethereal Plane, the spell fails and the spell slot is wasted). At the start of your next turn you return to an unoccupied space that you can see within 10 feet of where you disappeared from. If no unoccupied space is available within range, you reappear in the nearest unoccupied space (determined randomly when there are multiple nearest choices). As an action, you can dismiss this spell.

Until the spell ends, you are shrouded in distortion and your image is blurred.

A thin sheet of flames shoots forth from your outstretched hands. Each creature in the area takes 3d6 fire damage. The fire ignites any flammable unattended objects in the area.
