Disorient

You attempt to disrupt the sense of balance of up to 2 creatures within range.  Each target must succeed an Intelligence saving throw or be affected by this spell for the duration.

Before an affected target uses an action or tries to move it must make a Dexterity saving throw.  On a failure it falls prone and looses its movement for that turn, though can still use the dash action.  On a successful save it continues its turn.  An affected target makes the Dexterity save only once per turn.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can target one additional creature for each slot level above 2nd.
