Calls forth healing rains to blanket the area targeted by the Shaman, restoring X health to allies in the area every 2 sec for 10 sec.
Healing Rain is a new shaman ability that comes with Cataclysm, learned at level 83 for 25 80. It was first announced in the Cataclysm shaman preview.
Healing Rain is an area-effect heal-over-time (HoT) spell that calls down rain in a selected area, healing all players within it. There is no limit to the number of players who can potentially be affected; however, there are diminishing returns when healing a large number of targets, much like the diminishing returns associated with AoE damage spells. This should give Restoration shaman another healing tool that improves their group-healing and heal-over-time capabilities. It has a 2-second cast time and lasts for 10 seconds, with a 10-second cooldown, and a 30-yard range.
