Switchstep

You attempt to switch places with a creature within range. The target must succeed on a Strength saving throw, or you and the target swap positions, plus the target takes 1D4 force damage. 

The target can willingly fail the saving throw if it chooses, allowing it to be moved without resistance, they take not damage in doing this. If the target is unwilling, it must be no more than one size category larger than you.

Cantrip Upgrade. The damage increases by 1dd when you reach levels 5 (2d4), 11 (3d4), and 17 (4d4)
