Wild Magic Origin

See the PHB for Wild Magic details

Wild Magic Surge

Updated 1st-level Wild Magic feature

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, roll a d10. If you roll a number equal to, or lower than, level of the spell you cast, roll on the Wild Magic Surge table to create a random magical effect.

Origin Spells

You gain an origin spell at the noted Sorcerer levels. Once you gain an origin spell, you always know it and it doesn't count against the number of spells known.

If you have an origin spell that doesn't appear on the sorcerer spell list, the spell is nonetheless a sorcerer spell for you.

Whenever you gain a sorcerer level, you can replace one spell you gained from this feature with another spell of the same level. The new spell must be an evocation or transmutation spell from the sorcerer, warlock, or wizard spell list.
