Riptide
Rank 1/1
Heals a friendly target for 486 to 534, an additional 445 over 15 sec, and increases the effectiveness of your Chain Heal casts directly on that target by 25%.
Averages, counting crits and misses, for a level 60 Shaman with a typical weapon and no other gear or buffs, against a target your level. Worked out from the game's own data, the same way as the Foresight addon.
