NotesEdit

Patch 4.2.0 (28-Jun-2011): Improved Water Shield has been redesigned and renamed Resurgence. When Water Shield is active, Resurgence causes critical direct heals to restore mana (Resurgence rank 2 is roughly equal to 150% of the old Improved Water Shield value when a Healing Wave or Greater Healing Wave critically hits, and scaled down accordingly for faster or multi-target spells).
/ Patch 4.0.1 (12-Oct-2010): Reduced from 3 to 2 ranks. 30/60% chance added to Healing Surge, replacing Lesser Healing Wave.
Patch 3.2.0 (04-Aug-2009): This talent now has a 10/20/30% chance to be triggered by Chain Heal, and the charges of Water Shield are no longer consumed by this talent.
Patch 3.0.8 (2009-01-20): Lesser Healing Wave now has a reduced chance to trigger this talent.
/ Patch 3.0.2 (14-Oct-2008): Added.
