Any placeable object can mark terrain, but in order to be useful the marking object must be:
- Visible over a distance - in WoW, that generally means a large object
- If subtlety is warranted, a small object may server better
- Persistent - no fixed duration, but generally at least tens of seconds or several minutes
- Stays in a fixed location - if it wanders, it can't mark a spot on the map
- Smoke Flares are the quintessential example. The Smoke Flare pyrotechnic device places a smoke column on the terrain.
- Lunar Festival terrain markers. These two stones create a column of light on the terrain.
- Ad Hoc, generally smaller objects. Anything that can be placed; examples:
- A campfire, placed by using the Basic Campfire skill.
- A keg of Brewfest Brew, placed by using a (not consumed) - if you have the item, the use is free
- Summoning a Snowman companion (requires and consumes a )
- A Portal, summoned by a mage. It doesn't matter where the portal goes, it is being used for its graphic property in the game environment (requires and consumes a )
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
