Really Wild Magic

Basically it's wild magic sorcerer that adds damage modification and Chaos. Chaos is a new stat that increases your chance of wild magic happening but also increases a chance of some truly wild magic happening.

Wild Magic Surge

Starting when you choose this origin at 1st level, your spellcasting can unleash surges of untamed magic. Once per turn, the DM can have you roll a d20 immediately after you cast a sorcerer spell of 1st level or higher. If you roll a 1, roll on the Wild Magic Surge table to create a magical effect. If that effect is a spell, it is too wild to be affected by your Metamagic, and if it normally requires concentration, it doesn’t require concentration in this case; the spell lasts for its full duration.

Tides of Chaos

Starting at 1st level, you can manipulate the forces of chance and chaos to gain advantage on one attack roll, ability check, or saving throw. Once you do so, you must finish a long rest before you can use this feature again.

Any time before you regain the use of this feature, the DM can have you roll on the Wild Magic Surge table immediately after you cast a sorcerer spell of 1st level or higher. You then regain the use of this feature.

Also, when you roll damage, you may spend 1 sorcery point to either have your damage dice explode, or deal maximum damage. If you max your damage, roll 1d20, on a roll of 10 or greater, add 1 Chaos. If you explode your dice, roll 1d20, on a roll of 15 or greater add 1 Chaos.

Every time your wild magic triggers or other factors cause it, your Chaos increases by 1.

Cracked Magic

Beginning at 6th level the range that your wild magic triggers is increased by 1 for every 20 Chaos you have acquired.

Magical Rift

At 14th level, whenever you roll on the wild magic table, roll a second [roll]1d100[/roll]. If the result is lower than your Chaos, magic breaks into a chaotic blast. 

You explode with magical energy. Convert every sorcery point you have available into spell slots, starting with the largest possible, ignoring maximum spell slots (for those available at your level). All of your spell slots are now expended. Take 1d6 points of magical damage for each level of each spell slot expended in this way. Every creature within 100' takes damage as well without a save. Those within 10' take 3/4 the damage you took, those within 30' take 1/2 the damage you took, those within 60' take 1/4 the damage you took, those within 100' take 1/6th the damage you took.

Triggering this ability warps reality for a short time. Confer with your DM about the outcome of this magical event.

When you reach this level, you are able to immediately expunge either half of your current Chaos, or 30 points of Chaos.

Whenever you finish a long rest, you may reduce your Chaos by 5.

Conduit of the Weave

Beginning at 18th level, the chaos of your wild magic has become a boon to yourself more than it has become a hinderance. At any time you roll on the wild magic table, you may ignore the result. 

Also, once per long rest, you may channel the weave through yourself to have one of a number of affects.

1. Restore all expended spell slots to up to 5 creatures within 100' of yourself.
2. Cause a magical rift as per the 14th level ability.
3. Trigger any 1 affect on the wild magic table of your choice.
