Lucan opened the door the rampart from the top level of the eastern gate tower. They need to clear the kobold archers from the top of the walls if Sturdy's troops were going to survive an extended fight in the area between the wall and fortress.
The warlock's phantom warrior rushed out first, expending its last two charges, using telekinetic slam to knock four kobolds off the fifty-foot-tall wall.
Silent took her position in the door frame and started to shoot arrows. Lucan only needed to keep her safe until back up arrived.
The kobolds on the wall reacted quickly and turned their attention to the gate tower.
With a flick of his wand Lucan sent telekinetic slashes at the wrist of any kobold who was taking aim. His attacks caused their arrows to fire prematurely or off course.
