Riptide

Riptide is the 31 point talent in the shaman Restoration tree. It is an instant cast healing spell with a heal over time. If the shaman casts Chain Heal on the target while the Riptide buff is still up, it will consume the heal over time spell and give the chain heal a 25% increase in healing.

Improvements

 * Tidal Focus reduces the mana cost by 5%. Improved Water Shield returns mana every time the spell crits, further increasing mana efficiency.
 * Ancestral Awakening allows the spell to heal a secondary target for 30% of the initial heal if the spell crits. Note that this only affects the direct heal and not the heal over time part.
 * Ancestral Healing causes the spell to increase the target's armor when it crits.
 * Tidal Waves causes Riptide to decrease the casting time of your next two Healing Wave or Greater Healing Wave spells if cast within 15 seconds.
 * Glyph of Riptide increases the duration of the heal over time effect by 6 seconds.
