Curse of the Putrid Husk

This illusion forces the subject to believe his flesh is rotting and falling off his body, and that his internal organs are spilling out. If the target fails his Wisdom saving throw, he is horrified during his next round, suffers from the stunned condition, and takes 1d8 necrotic and 1d8 psychic damage. During each of the end of the target’s turns, the target can repeat his Wisdom saving throw (the difficulty of the saving throw decreases by 1 every round). Also, when the target takes damage, he can repeat his Wisdom saving throw with disadvantage (this is because the damage may contradict with the illusion - for instance, the damage inflicted may cause pain in an arm that the target believes has already rotted off). If the target succeeds on any of these saves, the spell ends. If he fails, he again takes the damage listed above and remains horrified (stunned).
