I understand everything, except why so many mounted combatants were selected to hold a interior position, and why fighters, who already have Tower Shield Proficiency, took it as a feat.  (If it was the Warriors, they would have had only two feats.... And I think Warriors may be proficient in Tower Shields as well, as their description simple reads 'all shields'.)<br/><br/>Finally, I also wanted the dimensions of the room we are defending, plus the two street positions, and if a room above the center of the lab was available for the ritual.  (Preferably one with some distance and stairs to travel away from the exit.)<br/><br/>When you say, "Mass Combat" I assume you mean the Warriors?  (Having already finished the fighters, thanks!)  I can equip and feat them up, certainly.  Seeing so many Horse specialists, as well as a ranged Cavalry Unit, and knowing the main foes would be undead...<br/><br/>
