Cosmic Canvas

You cast an illusion across the sky itself. For the duration, you can produce the following effects in range:

• Malleable Firament. As a bonus action, you change various aspects like the sky's colour, lightning, cloud cover, phases of the moon, and/or the positions, presence, or absence of heavenly bodies. Attempts to navigate using the sky as guidance are made at advantage for any creatures you choose within the area. You can also cause creatures you choose to have disadvantage on checks to navigate using the sky within the spell's area; if a creature becomes lost while suffering disadvantage this way, you choose the direction it travels for the first mile after becoming lost. You don't need to see a creature or know its location to target it with this effect.
• Phantasmagoria. As an action, you cause the sky in a 100ft radius area you choose within range to quickly change between night, day, and a series of other appearances you choose. Each creature within that area makes a Wisdom save or be incapacitated for 1 minute. An affected creature can repeat its save at the end of each of its turns, ending the effect on a success; once a creature passes the save, it's immune for the next 24 hours.
• True Sky. As an action, you change the sky to a condition such as dusk, midday, a new moon, or an eclipse. The illusion's so realistic that it triggers effects/properties within the spell's area that would activate at a certain time of day or at during a certain celestial event (such as a magic item regaining charges at dawn or a werewolf transforming at full moon). You can't use this effect again until you cast this spell again.
  While the caster concentrates on it, this spell can't end short of Wish. Including the caster in an Antimagic Field suspends this spell's effects.
