Blastback swipe

Blastback swipe is a spell of the evocation school used by some swordmages of relatively low experience and power, particularly those of the assault style. When cast blastback swipe causes debilitating sound to emanate from the swordmage's weapon as he or she swings it about a target with melee range. The sonic energy not only causes the creature injury, but if successfully used, pushes the target back up to ten feet. Assault swordmages gain an additional benefit from the spell and can use it as a component of their aegis of assault spell. The spell is easily recharged with a rest of a few minutes or more.
