Wild Magic Leak

You launch an ever-warping ball of wild energy at a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d6 psychic damage.

If you roll a Natural 1 or Natural 20 on the attack roll, roll on the wild magic table twice. 

On a Natural 20, the caster can choose which effect of the two to apply.

On a Natural 1, the DM chooses which effect applies.

Wild Magic effects affect the caster of this cantrip.

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
