Traits

Fungal Aura

A creature that starts its turn within 5 feet of a mindrot thrall must succeed on a DC 13 Constitution saving throw or become infected with the mindrot disease.

Mindrot

A creature infected with this disease manifests symptoms in 1d4 days after infection, which include migraines and muscle weakness. Until the disease is cured, at the end of each long rest, the infected creature must succeed on a DC 13 Constitution saving throw or take 9 (2d8) acid damage, and its hp maximum is reduced by that amount. This reduction lasts until the creature finishes a long rest after the disease is cured. The creature dies if the disease reduces its hp maximum to 0. One day after the creature dies, it rises as a mindrot thrall. A creature that succeeds on two saving throws recovers from the disease.
