Escalating Assault

Heroic Tier
Prerequisite: swordmage with aegis of assault
Benefit: Each time you make a melee basic attack granted by your aegis of assault power, you gain a cumulative +1 bonus on future attack rolls made for the melee basic attacks granted by this power (up to a maximum bonus of +3). This bonus resets to 0 at the end of the encounter or if you are rendered unconscious.
