New Disease: Tsathar Egg Infestation

Tsathar are sexless, reproducing by injecting eggs into living hosts. An egg can be implanted only into a helpless host creature. The host must be of Small size or larger.

Giant frogs, bred for this very purpose, are the most common host.

The symptoms of the infestation manifest when the creature next takes a long rest. The infected creature suffers one level of exhaustion. While it has any levels of exhaustion, it is paralyzed, does not benefit from a long rest, and cannot regain hit points from any source save for magic. At the end of each long rest, an infected creature must make a DC 15 Constitution saving throw. On a failed saving throw, the creature gains one level of exhaustion. When an infected creature dies, the young tsathar emerges.

A lesser restoration spell rids the victim of any implanted egg. In addition, another creature can attempt a DC 20 Wisdom (Medicine) check to remove an implanted egg surgically. Each attempt made deals 4 (1d8) slashing damage to a creature.

The type of creature and the implanting tsathar determines what type of tsathar emerges upon the death of the victim:

  • If the implanting creature is any type of tsathar and the victim is any type of beast, the emerging egg is a tsathar.
  • If the implanting creature is a sacerdotal tsathar and the victim is a humanoid, roll a d6. On a 1-3, the egg is a tsathar; a 4-5, the resulting egg is a sacerdotal tsathar. On a 6, it is instead a hellbender tsathar.
  • If the implanting creature is a hellbender tsathar and the victim is humanoid, roll a d6. On a 1-4, the egg is a tsathar. On a 5-6, the egg is a hellbender tsathar.
