- Depends on the setting, your class or another addon (details in the tooltip)
What it does
Checks if you have a totem active in the element slot you choose: Fire, Earth, Water or Air. An empty or expired slot does not match.
Why you might use it
For Shamans, tells whether any totem is active in one element slot (Fire, Earth, Water or Air). Use it with NOT to put a Fire totem back down when Searing Totem has expired, or to remind you that an Air slot is empty. Empty, zero-duration and expired totems do not match. On Retail and WoW Forever the game can hide totem slots, and the condition is unavailable then. See also Specific Totem Present and Totem Time Remaining.
Example
Fire totem is active
