If your prototyped realself died on a quest bed, would the resultant god tier can your sprite's features and powers from the prototypings.

Nope, only if they ascended on the Crypt or if the Prototyped one were the Dream Self- If it’s the Sprite who dies on the Quest Bed, and it worked, then the Dream Self would ascend with none of the features from the Sprite. The question here is IF a Sprite can ascend dying on the Quest Bed. I’d imagine yeah if it’s the Alpha? But it’s hard to tell.
