Assemble Monument, Greater

The diamond dust swirls from your hand and expands to form a cloud occupying a 30 foot radius sphere. Any creature entering or ending their turn within this sphere must make a Constitution save against you. Failing this save causes the creature to take 3d12 points of piercing damage and 4d12 points of slashing damage. Succeeding this save halves the damage. While in this sphere, a creature is blinded and deafened. When the spell finishes casting, the monument is conjured, taking the form of a randomly rolled trinket. All of the dust is blown away in a massive shockwave, and anyone in the sphere must make a Constitution save. Failing this save causes them to take 16d12 points of thunder damage, and succeeding halves the damage. Either way, a creature in the shockwave is sent flying 2d10 x 10 feet away from the monument, with their minimum distance from the monument placing them right at the edge of where the radius was. The complete monument occupies a 60x60 foot area and is not considered magical, unless the trinket rolled has magical properties.
