Wall of Mirrored Gate

A near invisible wall springs into existence at a point you choose within range. The wall appears in any orientation you choose, as a horizontal or vertical barrier or at an angle. It can be free floating or resting on a solid surface. You can form it into a hemispherical dome or a sphere with a radius of up to 10 feet, or you can shape a flat surface made up of ten 10-foot-by-10-foot panels. Each panel must be contiguous with another panel. In any form, the wall is 1/4 inch thick. It lasts for the duration. If the wall cuts through a creature's space when it appears, the creature must make a Dex Save against your spell DC, on a success it manages to move to one side of the wall (which side is determined randomly).

Nothing can physically pass through the wall. One side of the wall, selected by you when you cast this spell, is slightly reflective and anything that touches the wall's surface on this side must make an Int save or immediately vanish for 1d4 rounds, reappearing 1d10x5 feet away from the wall (approximately perpendicular) on the same side it originated. This includes melee attacks attempts. The wall has an AC of 15 & 75 hp per panel, it is immune to poison,  necrotic, psychic, radiant and all non magical damage except that done by silvered weapons. Attacks directed at or through the wall on the silvered side are absorbed and released directed back targeting its point of origin immediately before the same initiative count the next round, using its original attack role. This includes magical attacks excepting those of a higher level than the Wall was cast at, such spells affect the wall normally if it is the target or blocks the spell and takes half the spells damage. The wall also extends into the Ethereal Plane, blocking ethereal travel through the wall.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the distance increases by 1d10x5 feet for each slot level above 5th.
