Galvanizing Ward

Galvanizing Ward is a passive  skill in Diablo III. It is unlocked at character level 40.

In-game
Five seconds timer is reset if any unsaved damage is taken, even if it is fully absorbed. The Wizard must remain completely immune to damage or not be hit at all for the shield to regain power. Being hit by a non-damaging attack will not reset the timer.

Enhancements:

 * Ashnagarr's Blood Bracer (Legendary Bracers): increases potency by 75-100%.

Development
Prior to the pre-expansion patch for Diablo III, this passive granted the Wizard a doubled duration of effect for their Armor skills, and granted Life Regeneration when one of those spells was in effect.

Prior to patch 2.4, the shield absorbed a flat amount rather than a percentage of Life.
