A cloth made of silk from a rare aquatic spider. This cloth will hide anything it covers, but only in a place surrounded by water.
The instant the cloth covers something, the sheet changed to the colour of the surface of the water, making it hardly possible to see the hidden objects; however, enough light passes through the sheet for people hiding under it to see through it. The durability of the item decreases by approximately ten percent per five minutes when the item’s ability is activated. The lost durability can be restored by repairing it using the Tailoring skill.
