Arcane Trickster — Sagor från Valoris

The Arcane Trickster takes the rogue's oldest tools — the nimble fingers, the ready lie, the knack for being where no one expects — and threads them through with a strand of true wizardry. These are thieves who learned to cast, favoring the schools of enchantment and illusion: the magic of bending minds and bending sight, of misdirection made real. A locked door is no obstacle when an unseen spectral hand can turn the tumblers from across the room; a guard is no threat when a whispered charm turns them friendly.

It is the most cunning and self-sufficient of the archetypes. An Arcane Trickster picks pockets they never touch, casts spells no one sees coming, and at the height of their craft can even steal a spell out of an enemy's mind mid-casting. They are the burglar who has made the impossible routine — half rogue, half mage, and entirely too slippery to catch.

3rd Level

Spellcasting

You've stolen a wizard's craft for yourself. Drawing on Intelligence, you cast from the Wizard spell list, knowing Mage Hand and a handful of cantrips and preparing a small, growing set of spells — most of them drawn from the Enchantment and Illusion schools, the magic of charm and deception best suited to a thief's work.

3rd Level

Mage Hand Legerdemain

Your Mage Hand becomes a thief's third hand. You can make the spectral hand Invisible and command it as a Bonus Action, using it to stow or retrieve objects in another creature's pockets and packs, or to pick locks and disarm traps at range. With a Sleight of Hand check against their Perception, you can do it all entirely unnoticed — a pickpocket who never has to be within arm's reach.

9th Level

Magical Ambush

Your spells strike hardest from the shadows. If you have the Invisible condition when you cast a spell on a creature, that creature has Disadvantage on any saving throw it makes against the spell on the same turn — a charm or an illusion far harder to shrug off when the caster was never seen at all.

13th Level

Versatile Trickster

Your spectral hand joins the fight. When you use the Trip option of your Cunning Strike on a creature, you can also apply that option to another creature within 5 feet of your Mage Hand — the unseen hand yanking a second enemy off-balance from clear across the battlefield.

17th Level

Spell Thief

The ultimate pickpocketing: you steal magic itself. Immediately after a creature casts a spell that targets or includes you, you can take a Reaction to force an Intelligence saving throw (DC 8 + your Intelligence modifier + your Proficiency Bonus). On a failure you negate the spell against you — and if it's one you could cast, you steal the knowledge of it for 8 hours, casting it with your own slots while its owner can't cast it at all. Once used, you recover this on a Long Rest.
