Mark of Warding [Dragonmark]

Heroic Tier
Benefit: Whenever one of your powers grants a bonus to a defense, increase that bonus by 1.
Whenever you mark an enemy, that enemy takes a -3 penalty to attack rolls for attacks that don’t target you instead of the normal -2 penalty.
You can master and perform rituals in the warding category and the Fluid Funds, Knock, and Leomund’s Secret Chest rituals as if you had the Ritual Caster feat.
