Wild Magic and Shadow Magic Subclasses combined (Who knows if it is balanced.....)

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 an odd number, 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 Wild Magic, and if it normally requires concentration, it doesn’t require concentration in this case; the spell lasts for its full duration.

Eyes of the Dark

Starting at 1st level, you have darkvision with a range of 120 feet.

When you reach 3rd level in this class, you learn the darkness spell, which doesn’t count against your number of sorcerer spells known. In addition, you can cast it by spending 2 sorcery points or by expending a spell slot. If you cast it with sorcery points, you can see through the darkness created by the spell.

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.

Hound of Ill Omen

At 6th level, you gain the ability to call forth a howling creature of darkness to harass your foes. As a bonus action, you can spend 3 sorcery points to magically summon a hound of ill omen to target one creature you can see within 120 feet of you. The hound uses the dire wolf statistics (see the Monster Manual or appendix C in the Player’s Handbook), with the following changes:

• The hound is size Medium, not Large, and it counts as a monstrosity, not a beast.
• It appears with a number of temporary hit points equal to half your sorcerer level.
• It can move through other creatures and objects as if they were difficult terrain. The hound takes 5 force damage if it ends its turn inside an object.
• At the start of its turn, the hound automatically knows its target’s location. If the target was hidden, it is no longer hidden from the hound.

The hound appears in an unoccupied space of your choice within 30 feet of the target. Roll initiative for the hound. On its turn, it can move only toward its target by the most direct route, and it can use its action only to attack its target. The hound can make opportunity attacks, but only against its target. Additionally, while the hound is within 5 feet of the target, the target has disadvantage on saving throws against any spell you cast. The hound disappears if it is reduced to 0 hit points, if its target is reduced to 0 hit points, or after 5 minutes.

Bend Luck

Starting at 6th level, you have the ability to twist fate using your wild magic. When another creature you can see makes an attack roll, an ability check, or a saving throw, you can use your reaction and spend 2 sorcery points to roll 1d4 and apply the number rolled as a bonus or penalty (your choice) to the creature’s roll. You can do so after the creature rolls but before any effects of the roll occur.

Shadow Walk

At 14th level, you gain the ability to step from one shadow into another. When you are in dim light or darkness, as a bonus action, you can magically teleport up to 120 feet to an unoccupied space you can see that is also in dim light or darkness.

Spell Bombardment

Beginning at 18th level, the harmful energy of your spells intensifies. When you roll damage for a spell and roll the highest number possible on any of the dice, choose one of those dice, roll it again and add that roll to the damage. You can use the feature only once per turn.
