"The Smoker" is a secondary slot item for the pyro. It allows him to burst concerted smoke clouds to blind the enemy, to fumigate him or to extinguish fired places or burning friends.  A Smoke Cloud lightly damages enemies inside it, but it's easy to airblast it away. Once a Smoke Cloud is airblasted, it loses its density and damaging effect, but it floats fast over the ground. If you burst it with the Smoker only, it floats very slow, so that it nearly won't move. A fresh bursted cloud can hold on for 10 seconds and it becomes more powerful if you burst on the same place for a longer time. On the other side, such a powerful cloud just covers a small field. If you try to cover the whole place with clouds, this cloud won't do much damage, but can slightly block the view of an enemy. The Smoker has about 75 ammo and no reserved ammo. A good cloud with a high density can be burst with about 10 ammo-units. This Item is also more useful for tactical usage instead of making killing streaks, which actually means that the damage of the smoker isn't usually high.
