Nullification Shield

Nullification Shield was a generic level 20 Talent that could be activated to provide a massive amount of Spell Armor for a short duration. It was added with March 14, 2017 patch that introduced baseline Armor for various Heroes. It replaced Hardened Shield on Tyrael and Anub'arak as the patch shifted these Heroes more into anti-mage role. Following the removal of baseline Armor, the Talent was replaced with more general-purpose alternatives, including going back to Hardened Shield for Anub'arak.
