Hi Loriel.
Just a quick batrep about the setup I used in my last game according to the discussion we had.
On a 1650 pts game agaisnt the empire (1 general on griffin, 1 steamtank and a full cav bus with one priest wielding the duel mirror and another character), I lost quite badly.
Here was my set up :
Prince dragon armour, bardeed steed, shield, Star lance, Talisman of preservation, Khaine's ring 290 pts
Noble with ogre blade, enchanted shield, iron curse icon. 128 pts
Lvl 4 Qrchmage, book of Hoeth and Life magic. 275 pts
38 Spearmen 342 pts
5 Elyrian reavers 95 pts
2 RBT 140
1 Lion chariot of Chrace 120
6 Dragon Princes, BoWD, FCMD 254 pts
I took quite a beating. He got first turn. His steam tank blew 1 of my RBT. His cavbus advanced, his griffin flew for 20".
On my turn, my rtb does nothing, I forced march all my cav except my lion chariot. Put Throne of vines, and +4 Stm on my spearmen blob.
2nd turn he charges with his steamtank and annihilates my Dragon Princes. Only the Prince stays in combat. HE delays the charge of his cav-bus, but charges my Lion Chariot who flees out of the table.
I charge the Elyrian reavers into the steamtank flanks but not even one single Life point stripped. My Rbt does nothing to the cav-bus.
I march my spearmen.
3r Turn, he starts by charging the cav-bus into my blob. I launch a duel, he uses his mirror artifact and his priest swap characteristics with my duel noble

. I kill two of his knights, he kills 7 of my spearmen, despite +4regen, I lose the combat, roll a 10 on LD test, the blob flees, he run over me. Game Over.
Well that was quick

.
I know I've made several mistakes (march forcing the cav toward the steamtank, letting him inflitc so much dmg on me, I used the wrong spells at the wrong time, for ex I saved a lot of dice to ressurect dead cavalry, but there was only the prince left, so I couldn't raise any single member of the now destroyed unit, etc). Still, I think it might be better to do it high magic style like you did on some of your batreps.
