Misspelled Sorcery

Sometimes, an aspiring magician of any kind will suddenly manifest a speech impediment of mysterious, non-biological origin. Most spellcasters usually train this kind of trait out of themselves in speech therapy or quit the arcane arts entirely, but you were either persistent or you embraced its power. A close cousin to Wild Magicians, these types of sorcerers display a wild tongue that sometimes interacts with the mystic chanting and weaving of magic in odd, unpredictable ways. 

Level 1: Misspelling

Starting when you choose þis origin at 1st level, your speech impediment causes words to slipslide as you cast spells, sometimes causing þe spell's effect to change entirely. When you cast a spell of 1st level or higher wiþ a verbal component, roll 1d12. On a 1, þe spell is misspelled, causing you to roll a d4 and twist þe spell’s original intent. Þis can also be triggered if þe spell uses an attack roll, and a natural 1 is rolled to hit (such as Inflict Wounds).You and your DM come up wiþ þe possible misspelling options þat þe d4 consults, based on þe spell's name or effect, and usually it is best to have a table for each spell your sorcerer knows. Þe spell targets its original targets unless þe misspelling option says so. Here is an example, for þe spell Fireball:

1 - Liarball: þe spell targets its normal area, but deals no damage, and anyone who fails þe saving þrow can speak only lies for þe next 2d8 hours.

2 - You cast Fireball using a random Metamagic option, expending half þe sorcery points required to use þe option (rounding up). You don’t have to know þe option for it to trigger.

3 - Firewall: If you are playing in a setting wiþ computers, none of yours can be hacked for þe next two weeks - oþerwise, you cast Wall of Fire at its lowest available spell slot wiþ þe DM choosing its placement.

4 - Gyreball: þe spell targets its normal area, and instead deals magical Bludgeoning damage equal to þe original Fireball's damage, while also flinging anyone who fails þe saving þrow 15 feet in a direction of your choice (including up).

Wild Tongue

You gain proficiency in Persuasion and Deception, if you don't already have þem. Also, once per long rest, you can deliberately trigger your Misspelling feature and regain sorcery points equal to þe number rolled. If þis makes your current number of sorcery points an even number, you regain þe use of þis feature. You can recharge a maximum of half your Sorcerer level’s worþ of sorcery points, rounded up, wiþ þis feature.

Arcane Tonguetwister

At 6th level, your power becomes capable of affecting others' tongues. You can force an enemy spellcaster to misspell their spell, and fail to cast it correctly. When another creature you can see begins to cast a spell with verbal components, you can use your reaction in one of two ways:

Spell Destruction. You may use your reaction and spend 4 sorcery points to cast Counterspell without expending a spell slot and without the chance of the spell being misspelled.

Spell Garbling. You may use your reaction and spend 2 sorcery points to force them to Misspell as per your class feature (The DM makes the roll and determines the effect).

Hold Your Tongue

At 14th level, you gain a modicum of control over your and other tongues. When you Misspell, after seeing the roll you may negate the result of the Misspell and cast the spell normally once per long rest, or reroll at the cost of 1 sorcery point (the latter can be used as long as you have sorcery points). You can't use this second option on an already rerolled Misspell. You can also spend 1 sorcery point to cast Silence without expending a spell slot.

Error Spelling

At 18th level, you can now control your Misspelling to a degree. When casting a spell of 5th level or lower, you may expend sorcery points equal to its level to choose a Misspelling effect and use it instead of the spell's normal effect.
