Press the ] or [ key and select the 'bomb' or whatever it's called (the thing that mara picked up and she said 'u know, people shouldn't be lying these around, someone could get hurt.') well go up to the dome, and select that bomb thing and press enter.
Hope that helps.
Battle is a pure form of expression. It is heart and discipline, reduced to movement and motion. In battle, the words are swept away, giving way to actions-- mercy, sacrifice, anger, fear. These are pure moments of expression.
