Searing Totem is a core shaman ability learned at level 16. It is a reliable source of extra damage, and is useful in situations where the other damage totem ([Magma Totem]) isn't and/or when the [Fire Elemental Totem] is unfeasible.
When dropped, the totem randomly selects an enemy within range and continuously attacks until A.) the totem expires, B.) the target leaves range or C.) the target dies. If B or C occur, the totem randomly chooses another target in range and begins attacking it. If there are no targets within range, it does nothing until an enemy comes in range. Also note that the totem only engages hostile targets on its own; it ignores neutral targets, unless you engage them first.
It is useful primarily in single-target, prolonged fights (EG: Boss Fights). You should avoid using it in situations where it could accidentally hit a target that shouldn't otherwise be hit (such as something that has been CC'd).
Use: Permanently teaches you this glyph. When you cast a totem spell, you also place unempowered totems for any elements that are not currently active. These totems have 5 health and produce no other effects.
Very useful in PvP for an extra bit of consistent damage. Most players ignore the totem, knowing it will go away when you die.
Always useful in a boss fight, assuming the boss doesn't have adds which get CCed and the boss is not immune to fire.
Most of the time if you drop the totem while in melee, it will start attacking the target you have selected. This may be a function of closeness or may be a function of who you have selected at the time. It may simply pick the closest target when it doesn't have one.
It can be used to effectively disrupt spellcasting, especially in conjunction with melee attacks and a fast weapon. When combined with [Wind Shear], it can be difficult for an enemy caster to get out a spell.
Useful in PVP against another shaman. Searing Totem will often target and destroy the other shaman's totems.
