Stun grenade.

[Minato]

Its Actually a Great Idea but the Fgunz Community will hate this new grenade.
They already hate 1Hit Nades,Training Nades,Rocket Launchers well every sort of Explosion/Movement impaired stuff.

Plus we have a nade that has an element (fire, ice, and poison) and a smoke with poison. The ice nade can stun tho.
