When you cast a spell that has a casting time of an action you can spend 2 SP to change the casting time to a Bonus Action for this casting. You can't modify a spell in this way if you've already cast a level 1+ spell on the current turn, nor can you cast a level 1+ spell on this turn after modifying a spell in this way.
Your spellcasting can unleash surges of untamed magic. Once per turn, you can roll 1d20 immediately after you cast a Sorcerer spell with a spell slot.
If you roll a 20, roll on the Wild Magic Surge table to create a magical effect.
If the magical effect is a spell, it is too wild to be affected by your Metamagic.
You can manipulate chaos itself to give yourself Advantage on one d20 test before you roll the d20. Once you do so, you must cast a Sorcerer spell with a spell slot or finish a Long Rest before you can use this feature again.
If you do cast a Sorcerer spell with a spell slot before you finish a Long Rest, you automatically roll on the Wild Magic Surge table.
