Unstable Magic Surge

Starting when you choose this origin at 1st level, your spellcasting can unleash surges of untamed magic. Every time you cast a spell roll 1d20 to determine your spell's stability. This does not apply to reaction and social spells.

Untapped Power

Starting at 1st level, your lack of skills are compensated with raw power. Your max Charisma is increased by 4 to a max of 30, but you have -5 to Charisma and Arcana checks, and Disadvantage on all skill checks. You also add your spellcasting modifier to all spells.

Spell Fortitude

Starting at 6th level, due to the nature of your powers your constitution is higher than most and you've developed the ability to heal your allies with your words. Your Constitution score increases by 2, to a maximum of 20. You are granted advantage on Constitution saving throws. You learn the Mass Healing Word spell, but it doesn’t count against your number of sorcerer spells known. You cannot replace it with another spell.

Pierce the Veil

At 14th level, if you land a spell attack, you can choose to reduce the armor of your target by 4 for one turn, making your target more vulnerable to incoming attacks.

Critical Overload

Beginning at 18th level, the harmful energy of your spells intensifies. If you roll a natural 20 your spell does double damage or healing. However, you take 25% of the effect back to yourself as necrotic damage or healing.
