Constitution saving throw or gain one level of exhaustion. If an infected creature succeeds on the saving throw, it no longer gains exhaustion levels each day. A second successful save at the end of a long rest cures the disease. The abyssal disease resists many efforts at treatment and can only be cured by a greater restoration spell or similar magic. A living creature that dies from the effects of carrion curse has a 75% chance of rising again as a blood zombie (see page 393) within 24 hours.
