Sparfolk Blueprint

A magic item from the Elderdays, Sparfolk Blueprint wants magic brought into existence so that it may continue to exist by drawing on the lifeforce of magicians. A Sparfolk Blueprint cannot be attuned or controlled by any creature.

Additionally, the magician accues the following effects:

If the magical item is common, the magician suffers one level of exhaustion for 2 long rests
If the magical item is uncommon, the magician suffers two levels of exhaustion for 3 long rests (reduce to level 1 exhaustion after two LR)
If the magical item is rare, the magician suffers three levels of exhaustion for 4 long rests (reduce to level 2 exhaustion after two LR, reduce to level 1 exhaustion after three LR)
