concentration, 1 minute/mana

As two actions, a gravity vortex appears at a point that you can see within 100 meters. The gravity vortex is a cylinder twice as big as normal centered on that point. Until the spell ends, you can use two actions to move the gravity vortex up to 5 meters in any direction. The gravity vortex sucks up any Medium or smaller objects that aren’t secured to anything and that aren’t worn or carried by anyone.

Loose, lightweight materials brought into the gravity vortex fly upward. Arrows, bolts, and other ordinary projectiles launched at targets behind the gravity vortex are deflected upward and automatically miss. (Boulders hurled by giants or siege engines, and similar projectiles, are unaffected.)

A creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Reflex saving throw.

On a failure, it takes 1d6 bludgeoning damage and is restrained for the duration. At the start of each of its turns while restrained, the creature takes 1d6 bludgeoning damage and is pulled 1 meter higher inside it, unless the creature is at the top. A restrained creature moves with the maelstrom.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

A creature restrained by the gravity vortex can use an action to make a Brawn or Nimbleness check (its choice) against your spell save Difficulty. If successful, the creature is no longer restrained by the gravity vortex.

When the spell ends or if the creature escapes the gravity vortex, it is hurled 1d6 × 2 meters away from it in a random direction unless it has something to hold on to. If the creature falls it takes falling damage as normal, unless it has some means to stay aloft.

Augment

You can increase the damage by 1d6, you can affect a creature of a larger size, and you can increase the distance that the creature is thrown by 1d6 for each additional mana expended.
