Anamnesis

Memories of another life have been seeping into your dreams. Perhaps you were consecuted and have seen glimpses of multiple lives, or perhaps a soul has been merged with yours by some high-level magic. Perhaps you are a living construct, normally considered devoid of a soul, that an artificer has embedded a soul into. Regardless, these other memories have been brought to the surface, and with them, some of the abilities the other person possessed.

You gain access to spells from classes other than your current class as they return to your memory. You are still subject to the usual preparation limitations for your class and level, but otherwise, you have many more options afforded to you by the experience of past lives.
