The Z item, when obtained, slows the player down considerably, delaying every action that the player has, including taunting. This inability to react leaves the player suffering from its effects very vulnerable. If the player is killed when using the Z, their death animation will play through slowly until their spirit flies away.
A player who picks up the Z item has it for eight seconds. The Z should be avoided at all costs. If untouched for four seconds, it will disappear from the arena.
