Tilt & Mass Tilt

Tilt

1st level illusion
Casting Time: 1 Action
Range: 30 feet
Components: S, M (a small metal ball and spring)
Duration: Instantaneous
You twist a creature’s sense of balance and trick it into seeing the world shift beneath its feet. Choose a creature on a surface within range. The target must succeed on an Intelligence saving throw, or else fall prone and slide 20 ft. in a straight line in a direction of your choice. If the target would fall off a ledge as a result of this movement, it can make a Strength or Dexterity saving throw to prevent itself from falling and end the movement.
At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, you can target an additional creature for each slot level above 1st.

Mass Tilt

Casting Time: 1 Action
Range: Self (45 ft. cube)
Components: S, M (two copper tokens, which are consumed if no creature fails their saving throw)
Duration: Instantaneous
A wave of vertigo erupts from your hands as the world bends, spins, and collapses in the minds of your enemies. Choose any number of creatures within range. Target creatures must succeed on an Intelligence saving throw, or else fall prone and slide 20 ft. in a straight line in a direction of your choice. If the target would fall off a ledge as a result of this movement, it can make a Strength or Dexterity saving throw to prevent itself from falling and end the movement.
