You duplicate any 8th level spell or lower. There
are no requirements, it simply takes effect. Alternatively, you can create one item, heal, grant resistance or immunity, and force rerolls. Other possibilities may have consequences. Each time
you cast a spell before a long rest, take 1D10
necrotic damage per spell level. Your strength
drops to 3 for 2D4 days. There is a 33% chance
you will lose the ability to cast this spell
