Anyone consuming food or water contaminated by titan’s blood must make a DC 14 Constitution saving throw or suffer the effects of the ailment known as blood fever. Blood fever’s incubation period is 24 hours. When the incubation is complete, the victim reduces their hit point maximum by 5 (1d10), becomes poisoned until the disease is cured, and begins to convulse, literally sweating blood. The victim also hallucinates disturbing visions of violence and death. Every 24 hours that elapse, the infected must repeat the Constitution saving throw, reducing their hit point maximum by 5 (1d10) on a failure.

This reduction to the creature’s hit point maximum lasts until the disease is cured. The disease is cured on a success. The victim dies if the disease reduces their hit point maximum to 0. A character that dies in this way rises as a blood fever zombie one day after death.

Anyone who comes into physical contact with a victim of blood fever risks catching the disease as well, though the Constitution saving throw against contracting blood fever in this manner is DC 10. If a character makes a successful save, they are immune to contracting blood fever for 48 hours.

Blood fever can be cured by a lesser restoration spell and other similar effects.
