Healing Tide Totem is a Restoration shaman ability.
Tips and tactics[]
Healing Tide Totem is a healing raid cooldown which heals all allies within 40 yards of the totem for a small amount every two seconds for ten seconds. It is used mainly in group play and should be used whenever the shaman's party is sustaining heavy, continuous amounts of damage. In five-player parties, it is up to the shaman's discretion when to use it, but in a raid setting it is best to coordinate with the party's other healers on when it (and the other healing cooldowns available) will be used.
The healing provided by Healing Tide Totem is strong, but still much weaker than restoration druids' [Tranquility]. Healing Tide Totem does, however, have a tremendous advantage in that it does not need to be channelled. In raid situations where Tranquility-like throughput is needed for survival, the shaman is still free to place their totem and then cast [Chain Heal], [Healing Wave], [Riptide], etc. to counter the damage that exceeds what the totem is capable of on its own. Also, Healing Tide Totem can efficiently counter effects that do heavy damage but also requirement movement, as it can be placed just before movement is needed and heal the shaman and her allies as they move.
