Walk of Depiction

Using a menagerie of fine inks, you paint and magically infuse a portrait that depicts a location of a place. Make a DC 15 Intelligence (History) check to determine if the infusion is successful. You make the check with advantage if you have been to the location itself from the perspective you have painted, or you have access to that photographic information through means such as a real painting or the use of a thought strand. Upon a successful infusion, the painting will glow and warble like the surface of water, letting off a soft moonlit glow, the images depicted appear to float in three dimensions as if peering through a small window. Creatures that look through an infused painting will see an accurate reflection of what is happening at the location depicted. A large or smaller sized willing creature may use an action to reach into the infused painting, transporting itself to the exact position of the perspective's origin. Alternatively, an unwilling creature may be shoved into the painting. A transported creature will emerge from a large, glowing, ethereal portrait on the opposite end. They cannot return the same way without another casting of this spell. The magic infusion and the ethereal portrait vanish after 1 day.

You may focus your casting on an existing painting in the world instead of creating a depiction from scratch, in that case, the material cost is reduced to 500gp.

If the successful infusion was instead made with a general description of somewhere (e.g. "a hilltop castle looked down upon by dark clouds and surrounded by a rainforest"), the DM can decide to have it appear in a location that fits the description, provided it was accurate enough.

If the successful infusion is a fictional location, the painting will instead lead to a newly created, unstable demiplane, accurately reflecting that painted location as best as possible at the DM's discretion. The demiplane will collapse 2d8 hours after casting. Anyone caught in the demiplane's collapse will take 6d10 force damage and appear in a random unoccupied space on the same plane of existence the spell was cast from, 15 miles from the original casting position.

If the location depicted is of a different plane of existence to the one the caster is currently on, the spell fails as the paint melts away and the canvas collapses immediately.
