Smoke Flare

A Smoke Flare is a pyrotechnic device used primarily to mark a location on the terrain. The Smoke Flare item does this by placing a smoke column object on the terrain.

Any placeable object can mark terrain, but in order to be useful the marking object must be:
 * Visible over a distance - in WoW, the Smoke Flare smoke column are as visible as any large object gets.
 * Persistent - the Smoke Flare smoke columns persist for five minutes.

Some uses that people have come up with:
 * marking locations for raids
 * smoke bomb the Flag Rooms in the Warsong Gulch battleground
 * props for floor shows and fashion shows
