Sight Rot

This painful infection causes bleeding from the eyes and eventually blinds the victim.
A beast or humanoid that drinks water tainted by sight rot must succeed on a DC 15 Constitution saving throw or become infected. One day after infection, the creature’s vision starts to become blurry. The creature takes a ?1 penalty to attack rolls and ability checks that rely on sight. At the end of each long rest after the symptoms appear, the penalty worsens by 1. When it reaches ?5, the victim is blinded until its sight is restored by magic such as lesser restoration or heal.
Sight rot can be cured using a rare plant called Glimmershade, which grows in Glimmershade, or Eyebright which grows in some swamps. Given an hour, a character who has proficiency with an herbalism kit can turn the flower into one dose of ointment. Applied to the eyes before a long rest, one dose of it prevents the disease from worsening after that rest. After three doses of Eyebright or one of Glimmershade, the ointment cures the disease entirely.
