Unleashed Arcanists are sorcerers who have immense raw magical power but have little to no control over it. Their spells are unpredictable and unstable, often resulting in unintended consequences. Unleashed Arcanists are feared and respected for their immense power, but their lack of control makes them dangerous to themselves and those around them. the more they use their magic, the shorter the passage between them and raw magic, if they gain too much power they will likely end up killing themselves and all around them. the spellcasting of this subclass functions in a unique way. With the power these sorcerers have access to, spell slots are more like suggestions. These sorcerers have significantly less spell slots, but spell slots to them are simply assurances the spells will work. 

personally, I always thought sorcerers are supposed to be way overpowered, but with massive drawbacks, I played this subclass in a game I GM as an npc, and it worked really well with the theme of sorcerers.

also, there are lots of options, it will say what it replaces, it only really works if you stick to the bold text, but do what you will :)

 

unleash arcana

at level 1

draw from raw arcana to cast spells without spell slots, roll a charisma saving throw, equal to 12+ (the spell's level), on a fail, roll on the raw arcana table and make a constitution saving throw of the same dc or take a level of exhaustion. You can only attempt this on a spell level lower than your highest level spell.

01 - a fifth level fireball emits from where you stand, everyone within 20ft makes a Dexterity saving throw, or takes 10d6 damage

02- everyone within 10 ft make a Constitution saving throw or take 4d10 necrotic damage, you gain the total number of hit points back.

03- cast a 4th-level confusion spell entered on yourself

11 - instantly go unconscious, you are automatically stabilized

12- you cannot cast spells for 1d4 rounds

13- become completely paralyzed for 1 minute, can only be cured by a lesser restoration spell or a healing spell of 4th level or higher
