Mirrorkin

One of your ancestors came from beyond the looking glass; a strange world where everything is a twisted reflection of the true reality. As such, you have inherited amazing powers of mimicry and illusion that allow you to copy other people’s abilities. To fight against you is almost akin to fighting one’s own mirror image, something few warriors would relish.

Dummy Feature

To get past DNDBeyond's stupid requirements

MIRROR MAGIC

When you choose this origin at 1st level, you can duplicate the magic that you would not normally have access to by learning spells that do not exist on the sorcerer spell list. The spell must not require an attack roll or a saving throw.

You can only learn a spell if it is of a level for which you have spell slots. You can learn one1st-level spell using this ability, which doesn’t count against the total number of sorcerer spells you know. Each time you gain a level, you can learn one additional spell this way. The spells learned need not be from the sorcerer spell list, but count as sorcerer spells for you. You can swap out one spell you learnt this way for another over a Long Rest

MIMIC TRAIT

Also at 1st level, you gain an uncanny ability to mimic other people. As an action, you can choose a creature you can see within 60 feet and gain one trait of your choice that they possess from the following list (even if they only possess it temporarily):

• One special sense, such as darkvision or tremorsense
• One movement speed, such as a swim or climb speed
• One skill, tool, or instrument proficiency
• One damage resistance
• One condition immunity
• Their accent, verbal tics, and mannerisms

You can keep this trait as long as you are within 60 feet of the target, or until you use this ability again.

REFLECT MAGIC

At 6th level, you can turn your skin into a shimmering mirror that reflects magic. You have advantage on saving throws against being charmed or frightened.

In addition, whenever you or a creature you can see within 120 feet of you succeeds on a saving throw against being charmed or frightened, you can use your reaction to force a different creature you can see within 120 feet of you to make a Wisdom saving throw against your spell save DC. If the save fails, the target is charmed or frightened by you (your choice) for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a successful save.

DAZZLING BRILLIANCE

Beginning at 6th level, when you cast an illusion spell of 1st level or higher, you can cast it by spending a number of sorcery points equal to the spell's level. When cast this way, the spell doesn't require concentration, and you can use your action to change the nature of the illusion, provided that you can see the illusion.

COPYCAT

By 14th level, you have developed your mimicry to the point where you can mirror the unique and powerful abilities of those around you. As an action on your turn, you can perform any action that has been performed within the last minute by a creature (other than yourself) that you can see within 60 feet. Any prerequisites that would normally be required for the action (such as brandishing of holy symbols, spending of ki points, or consumption of items) are waived when you use this feature, unless it is a spell or required the use of a spell slot, in which case you must still expend the relevant spell slot and any required expensive material components. If the ability forces targets to make a saving throw, you can use your sorcerer spell save DC.

Once you use this ability, you must finish a short rest before you can use it again.

PERFECT DUPLICATE

At 18th level, you can duplicate yourself and others with ease. You learn the spells disguise self and mirror image if you do not know them already, and you can cast them at will without expending a spell slot.
