Dussāvudha
Dussāvudha：One of the four most effective weapons found in the world．
It belonged to ālavaka．If he threw it up into the sky，no rain would fall for twelve years； if he let it fall on the earth，all plants and trees would die and nothing would grow for twelve years； if he threw it into the sea，the sea would completely dry up； it could make Sineru crumble into pieces．ālavaka hurled it at the Buddha，but it fell at the Buddha’s feet and remained there as a rug．
It is also called Vatthāvudha，and was evidently made of cloth
