Bloody Sphere

You form a sphere of blood with a 10-foot radius on a point within range. You must have blood sources within range totalling up to at least 4 medium or 1 large creatures worth of blood(roughly 6 gallons). The sphere can hover in the air, but no more than 10 feet off the ground. The sphere’s area is Heavily Obscured. The sphere remains for the spell’s duration.

Any creature in the sphere’s space must make a Strength saving throw. On a successful save, a creature is ejected from that space to the nearest unoccupied space outside it. A Huge or larger creature succeeds on the saving throw automatically. On a failed save, a creature is restrained by the sphere and is engulfed by the blood. At the end of each of its turns, a restrained target can repeat the saving throw.  Any creature restrained by the sphere makes a wisdom save or they become frightened until they leave the sphere. They can repeat this save at the end of each of the returns. The sphere can restrain a maximum of four Medium or smaller creatures or one Large creature. If the sphere restrains a creature in excess of these numbers, a random creature that was already restrained by the sphere falls out of it and lands prone in a space within 5 feet of it.  As an action, you can move the sphere up to 30 feet in a straight line. If it moves over a pit, cliff, or other drop, it safely descends until it is hovering 10 feet over ground. Any creature restrained by the sphere moves with it. You can ram the sphere into creatures, forcing them to make the saving throw, but no more than once per turn.  When the spell ends, the sphere falls to the ground and extinguishes all normal flames within 30 feet of

it. Any creature restrained by the sphere is knocked prone in the space where it falls.
