Alkis' Wild Surge

Level: 5th
Casting Time: 1 Reaction
Range: 30 feet
Components: V,S,M (A bullet)
Duration: Instantaneous
School: Diviniation 
Description: As a reaction you can force any creature within 30 feet to pass a Charisma saving throw to re-roll any melee or Ranged attack, spell attack, saving throw, or check that it just rolled (they can willingly fail this saving throw). On a failed save, the target re-rolls the dice it just rolled, using the new roll instead.
Once the new roll is resolved, wild magic surges around you. Roll a d6 and reference the effect associated with the roll below:

1. You cast fireball as a 3rd level spell centered on yourself.
2. For the next minute, you regain 5 hit points at the start of the each of your turns.
3. You vomit forth 10 pounds of snow.
4. You turn into a potted plant until the start of your next turn. While a plant, you are incapacitated and have vulnerability to all damage. If you drop to 0 hit points, your pot breaks, and your form reverts.
5. You regain your lowest-level expended spell slot.
6. You are resistant to all damage for the next minute.
