From D&D Wiki
|Casting time:||1 action|
|Components:||V, S, M (an adamantine lodestone with your true name carved upon it, worth 2000 GP)|
You call upon the limits of arcane possibility to transform your deterministic form into one of probability. You become a probability cloud, centered on where you cast the spell, occupying a sphere of a radius of 10 feet times 1d6 + your spellcasting ability modifier. Within this sphere, you can be simultaneously in two places at once.
Each turn you can choose to create and/or destroy a copy of you within the spell's area. You can have up to your spellcasting ability modifier of copies simultaneously. Such copies are not duplicates; they are all simultaneously you. If one copy takes damage, they all take damage; if one copy expends a spell slot or use from a magic item, all copies lose the same slot or charge. The copies all act on your initiative and can make only a move action on the turn they are created; after that, they may act normally.
The copies do not share concentration; whilst they are all part of the same being, they are different possibilities, and each possesses its own autonomy.
You can continue to exist within the probability cloud, even when no copy is in existence, simply remaining as an uncollapsed probability cloud. Whilst in this form, you are immune to all damage and have blindsight within the spell's area. Even when copies are present, you still maintain these benefits – the ‘Original’ you still exists in the cloud.
The spell ends when the duration runs out, you are reduced to 0 hit points or one of the copies leaves the area, either by leaving the sphere or entering an area of antimagic, such as that created by the Antimagic Field spell. When the spell ends you can choose one of your copies; if the spell ended due to a copy leaving the area, you must choose that copy. All other copies wink out of existence as the probability cloud collapses back into one person.
If the spell ends when you have no copies in existence, you coalesce back into existence next to the lodestone which is the material focus for this spell, and which remains behind when you cast the spell, forming a copy which becomes you. If the lodestone is no longer within the spell’s area, you simply wink out of existence; you cannot be raised by anything less than a Wish spell, as even your soul no longer exists.
