The Orb of Transmutation will upgrade a Normal item to a Magic item with 1x Modifier
A Regal Orb will turn any Magic item into a Rare item with 3x modifiers
You cannot upgrade a Rare item into a Unique item via similar currencies – Rare is the highest tier you can upgrade Path of Exile 2 items.
There are three ways to get Orb of Transmutation and Regal Orb currencies: by finding them as world drops (from mobs, chests, etc), buying them from certain vendors, or by Disenchanting gear of the associated rarity.
By Disenchanting Magic (blue) items, you will acquire Transmutation Shards.
When you get 10x Shards, you will create a full Orb of Transmutation.
By Disenchanting Rare (yellow) items, you will acquire Regal Shards.
When you get 10x Shards, you will create a full Regal Orb.
These currencies can drop randomly from world mobs, and may show up in the Buy Or Sell inventories for vendors throughout your journey. Be sure to check everything that drops off enemies and check vendor inventories whenever you portal back to camp for these PoE upgrade currencies.

Exalted Orbs will add a Modifier to any Rare item, up to a maximum of 6x Modifiers
