Staff of wondrous smells
Staff of Wondrous Smells is a magical quarterstaff. It can be of any of the materials that staffs are normally made of, and a ruby is on the tip of the staff. It is slightly lighter and packs heavier punch than a usual quarterstaff.
When it strikes an enemy in combat, it sometimes creates a cloud of macial scents. One of two things can result. If a blue cloud is created, it is dropped on the PC. By staying in the cloud, the PC gains many positive intrinsics - Infravision, Haste, Telecontrol, Polycontrol, ESP, Levitate. If a red cloud is created, it is dropped on whatever enemy you just hit with the staff. It confers many negitive intrinsics, most of which aren't listed on the status line. As far as I can tell, you can get Teleportitis, Polymorphitis, slow, and dizzy from this. You, for apparent reasons, can not lose your sense of smell from the cloud, however.
Although the blue cloud will always be dropped on the player and the red one always put on mobs, once the clouds appear they do stay there for a while, which means that a monster can wander into a blue cloud and vice versa if you are not careful, and the result can be dangerous.
