By weaving five hand signs and using Decay Release, Ryuk Levi can make a entire field into a swampland. But first it needs preparation, first either using water or making a body of water Ryuk can make that water murky and full of bacteria and fungi. Then using the existing earth, he makes the plants in the area grow fungi from them or just make fungi grow from the earth (they are not plants). If a person touches any of the fungi with their skin, the bacteria or fungi will enter the body and eat at things internally. Also if he wants he can make a certain bacteria grow that upon contact with the skin, the bacteria eats away at the skin and even bone if it gets that far. But this technique is used to give a huge advantage to Ryuk during certain situations.
