Eruption of Material Shape

You transmute a distant point across a continuous surface you are in direct physical contact with, such as solid ground or a wall, reshaping its material form. When choosing a point within range, you must determine the distance required to reach the targeted location, which is measured along the surface, as the magic travels through its continuous span rather than manifesting directly at the chosen point (for example, if you're standing on the ground floor of a room and target an area on the ceiling, you must measure the path from your position to the ceiling across the surface, accounting for any inclines, such as vertical walls required to reach the target).

At the chosen point, a 5-foot-wide, 15-foot-tall structure of the same material as the surface erupts from the ground. This structure can take any shape of your choosing, provided it retains the same dimensions. Each creature of your choice within 5 feet of the structure when it appears must make a Dexterity saving throw, taking 5d6 damage that is either bludgeoning, piercing, or slashing (your choice, depending on the form of the structure), or half as much on a successful one. This damage counts as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

After the spell is cast, the structure persists, becoming a nonmagical object formed from the original material until destroyed.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can create one additional structure for each slot level above 2nd. Each structure must originate from a continuous surface you are in contact with, and you can place it at a different point within range, or combine it with others by placing them adjacent to or stacked upon one another. When structures are combined in this way, they are treated as a single larger structure for the purposes of this spell, and the spell's damage is not increased.
