Moving swiftly, Tylara tucks her blade under her left arm as she speaks the harsh draconic words of a spell. She gestures sharply at the orc closest to the edge and a brace of force missiles (1d4+1=2, 1d4+1=4) streak forth to strike the orc. I hope he's clumsy she thinks fleetingly as the missiles hit him where he stands on the edge of the drop.
Tylara sends missiles of force into the orc standing nearest the edge. He shudders, stumbles, and falls downward with a shriek. Kerlan hurls a dagger of flame into the other orc, who immediately erupts into a brief ball of flams and then lies still.
Tyara sees the crumpled form of the orc she sent over the edge, and as she nears the edge, she sees a study ladder leading downward. No other orcs are immediately evident.
