Adiyy

The is an semi-blind insect residing within the banana grove outside of Omonporch. Because of their limited vision, they will not attack first, even if they spot a creature that they are hostile to. They will only fight back once they were already attacked.

Their will inflict victims with monochromed for 50-100 turns if it penetrates, and blurry vision if it penetrates again in another attack before monochromed wears off. Given enough time, this blurry vision will progress to monochrome.

Tips
The adiyy has no ranged attack, and requires the attack to penetrate in order to infect any creature with monochrome. This means that attacking only with ranged attacks, having high AV, or high DV are all viable ways to avoid infection. They will be constantly flying, so ranged attacks are usually the only way to hit an adiyy.

Their high level also means that once the proper precautions are taken, killing adiyys along with and  are decent sources of late game exp.
