Players choosing to create a sorcerer in Mirrorworld can not take the Draconic sorcerous origin. Sorcerous origins can be either Wild Magic or Shadow (described below).

Altered Class Feature

Hit Points at Higher Levels: 1d4+2 (or 4) + your Constitution modifier per sorcerer level after 1st.

Sorcerous Origin: Wild Magic

The sorcerer’s can either come from a region in the Periphery magic zone, or have at least one sorcerous parent that did.

Sorcerous Origin: Shadow

Your innate magic comes from the Shadowfell. You might trace your lineage to an entity from that place, or perhaps you were exposed to its fell energy and transformed in some fundamental manner.

The power of shadow magic casts a strange pall over your physical presence. The spark of life that sustains you is muffled, as if it struggles to remain viable against the dark energy that imbues your soul. At your option, you can pick from or roll on the following table to create a unique quirk for your character.

Shadow Sorcerer Quirks (d6 Quirk)

You are always icy cold to the touch.
When you are asleep, you don’t appear to breathe (though you must still breathe to survive).
You don’t seem to bleed, even when badly injured.
Your heart beats once per minute. This event sometimes surprises you.
You have trouble remembering that living creatures and corpses should be treated differently.
You blinked. Once. Last week.

Eyes of the Dark

From 1st level, you have darkvision with a range of 60 feet. You can cast darkness by spending 1 sorcery point. You can see through any darkness spell you cast using this ability.

Strength of the Grave

Starting at 1st level, your existence in a twilight state between life and death makes you difficult to defeat. Whenever damage reduces you to 0 hit points, you can make a Constitution saving throw (DC 5 + the damage taken). On a success, you instead drop to 1 hit point. You cannot use this feature if you are reduced to 0 hit points by radiant damage or by a critical hit.

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 summon a hound of ill omen to target one creature you can see. The hound uses a dire wolf’s statistics with the following changes:

The hound is size Medium.
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 makes opportunity attacks, but only against its target. Additionally, the target has disadvantage on all saving throws against your spells while the hound is within 5 feet of it. The hound disappears if it is reduced to 0 hit points, if its target is reduced to 0 hit points, or after 5 minutes.

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 teleport up to 120 feet to an unoccupied space you can see that is also in dim light or darkness.

Shadow Form

At 18th level, you can spend 3 sorcery points to transform yourself into a shadow form as a bonus action. In this form, you have resistance to all damage except force damage, and you can move through other creatures and objects as if they were difficult terrain. You take 5 force damage if you end your turn inside an object. You remain in this form for 1 minute.

Sorcerous Origin: Storm

Your innate magic comes from the power of elemental air. Perhaps you were born during a howling gale so powerful that folk still tell stories of it. Your lineage might include the influence of potent air creatures such as vaati or djinni. Whatever the case, the magic of the storm permeates your soul.

Storm sorcerers are invaluable members of a ship’s crew. Their magic allows them to exert control over wind and weather in their immediate area. Their abilities also prove useful in repelling attacks by sahuagin, pirates, and other waterborne threats.

Stormborn

The arcane magic you command is infused with elemental air. You can hear the thoughts and emotions of Aedra in the wind. In addition, you gain the following spells at the listed sorcerer level. These spells do not count against the number of sorcerer spells you know.

Storm Sorcerer Bonus Spells

1st: Fog cloud, thunderwave
3rd: Gust of wind, levitate
5th: Call lightning, sleet storm
7th: Conjure minor elementals,* ice storm
9th: Conjure elemental**

* Unless you gain this spell from another source, you can summon only smoke mephits, steam mephits, ice mephits, or dust mephits with it.
**Unless you gain this spell from another r source, you can summon only air elementals with it.

Tempestuous Magic

At 1st level, you are attuned to elemental air magic. Whenever you cast a spell other than a cantrip during your turn, whirling gusts of elemental air surround you. You can use a bonus action to fly 10 feet without provoking opportunity attacks.

Heart of the Storm

At 6th level, you gain resistance to lightning and thunder damage. Whenever you cast a spell other than a cantrip that deals lightning or thunder damage, a stormy aura surrounds you. In addition to the spell’s effects, creatures of your choice within 10 feet of you take lightning or thunder damage (choose each time this ability activates) equal to half your sorcerer level.

Storm Guide

At 6th level, you gain the ability to subtly control the weather around you.

If it is raining, you can use an action to cause the rain to stop falling in a 20‐foot radius centered on you. You can end this effect as a bonus action.

If it is windy, you can use a bonus action each round to choose the direction that the wind blows in a 100‐foot radius around you. The wind blows in that direction until the end of your next turn. You have no ability to alter the speed of the wind.

Storm’s Fury

At 14th level, the storm energy you channel through your magic seethes within your soul. When you are hit by a melee attack, you can use your reaction to deal lightning damage to the attacker equal to your sorcerer level. The attacker must also make a Strength saving throw, with a DC equal to 8 + your Charisma bonus + your proficiency bonus. On a failed save, the attacker is pushed in a straight line 20 feet away from you.

Wind Soul

At 18th level, you gain a flying speed of 60 feet and immunity to lightning and thunder damage.

As an action, you can reduce your flying speed to 30 feet for one hour and choose a number of creatures within 30 feet of you equal to 3 + your Charisma modifier. The chosen creatures gain a flying speed of 30 feet for 1 hour.
