Restorative Waves is a passive Restoration shaman ability that directly improves the shaman's healing output.

Notes

In addition to increasing the effect of 'conventional' healing spells like [Chain Heal] and [Earth Shield], Purification also has some less obvious applications, although some of these might be unintentional:

The talent increases the healing done by [Ancestral Awakening], causing the secondary target to be healed for 12.5/25/37.5% of the initial heal, rather than 10/20/30%. This is in addition to the 25% that the initial heal was increased by.
While it is not a shaman spell, [Lifeblood] still benefits from Purification.
