Monster Hunter Rise players will need to gather all sorts of items and materials in order to craft powerful weapons and armor sets. One of the items, or bugs rather, that players might be on the hunt for is called Toxic Kumori. This insect can't be found out on quests or in any of the biomes; however, it can be obtained by going over to the Buddy Plaza and using the services that Rondine the Trader offers at the Argosy.
