The military regiment my PCs are part of will soon be assulting a Dwarven (I refuse to call them Squats) Stronghold (mainly because one of my players wanted to see Dwarves in the game, so I figured what better way than in brutal warfare?) and I need some ideas how to present the Dwarven defense in a unique and interesting fashion - something different enough to make the experience memorably Dwarven. Mostly what I need is ideas for the military defense they will encounter on the field of battle ... what kind of weapons and strategies will the Dwarves use to make the humans go "OH!!", etc.
Thanks.
