Starting when you choose this origin at 1st level, your spellcasting can unleash surges of untamed magic. Immediately after you cast a Sorcerer spell of 1st level or higher, the DM can have you roll a d20. If you roll a 1, roll on the Wild Magic Surge table to create a random magical effect.
Also at 1st level, you can manipulate your Wild Magic Surges, at a price.
Whenever you have to roll on the Wild Magic Surge table, you can choose the result of the surge. When you do this, you become Overcharged.
