your ideology is great but you dont get a trex until reha which is really late in the game. They are good units but they give dragons bad morale so i never use them. Im pretty sure i gained 2 or 3 levels just from that one fight though. necromancers are incredible units but you cant ressurect them so they really dont help on a no loss challenge. Plus, they got rid of the tolerate skill in AP which really pissed me off so the only undead unit i use are bone dragons in correlation with the other dragons. They really increased the stats of bone dragons since they were so weak in KB:TL so now i like them. Also, you dont need any useful spells until the end of the game. As long as you have poisen skull, fear, magic spring, and fire arrow, your in the clear at any point before elon. vampires are too slow and when you change into a bit they suck so i really dont use them either. Stick with high hp, level 5 units who can run away when your in a bad situation i.e. dragons and archdemons
