It's a sword-staff or something. It can be used to attack, but its special hability is guide that bug and make it attack monsters for you. Also, the bug can obtain "extracts" and give it to you. These extracts will give you buffs similary to the Hunting Horn (withe: speed, red: attack, green: healt, yellow: stamina). Thanks to this caracteristic hability, it has been named as a "Insect Staff", or something similar (let's waith for the official western name)
