Displace Ailment

You cause a malady to be redirected at another creature.

Choose two creatures within range, with one of them suffering from a condition or disease. The condition or disease ends on the afflicted creature - if the creature is unwilling to have this condition or disease removed, they must make a Charisma saving throw, with the condition or disease ending on a failure. 

The second target you choose must make a Constitution saving throw - on a failure, the target is afflicted by the condition or disease that the previous creature was afflicted with, and suffers from it for the spell's duration.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, both creatures must make their saving throws at disadvantage.
