Deathward Aegis is a heroic tier feat.
Prerequisite: Shadar-kai, swordmage, Aegis of Shielding class feature
Benefit: When you reduce damage with your Aegis of Shielding class feature, the same target also gains resist necrotic 5 until the end of its next turn. Increase this resistance to resist necrotic 10 at 11th level, and again to resist necrotic 15 at 21st level.[DrMA][Dr372:9]
