This spell is one of the most useful AAs you get.
This AA is bought by shamans in the omens tab. This aa Ability Stacks with any other heal over time spell(excuding if it was casted by another shaman).
This AA ability is Instant cast, increases your group stats a little, and of course heal over time what could you ask for more? Well it works with TGB (Target group buff) and theres no level restriction on who you cast it on (Castable even on the level 1s!).
The greatest thing is its MGBable, thats right you can MGB ancestral aid, No casting either, you can help your raid by pressing two buttons MGB and Ancestral aid and your raid or people around you will get wonderful Heal over time increasing their life span a little longer.
Additional note this AA can crit heal if you have the HoT series banked
