Vyukris's Gravity Pocket

The caster creates a very small, nearly invisible pocket of gravity at a point they choose within range, creating a 15' spherical area of flying debris. For the duration, anyone and anything which starts their turn within, or makes contact with the affected area, must make a Strength Savings Throw. On a failure, the target is caught up in the gravitational pull and becomes part of the debris field, taking 2d8 Bludgeoning damage per round. Target may reattempt the save at the start of each round.

When used with a spell slot above 4th level, the affected area causes an additional 1d8 Bludgeoning damage and grows 5ft larger, for each additional level above 4th.
