Sorry for the double post... I hate to do it, but it has to be done
Karador bit the big one tonight. The party that dropped him consisted of:
Horsemen
Demons (furious skill, always retaliates, better than a griffin)
Inquisitors
Priests
Archmages
I put the priests and the inquisitors in one corner and used them to gradually reduce the numbers of the enemy. I may have accidentally sold necro call, but xeona's castle had that spell and it was pivotal in this battle. As soon as an enemy dies, use the spell and get yourself an ally. You don't really need to level it up a lot - a simple lvl 1 will do. At lvl 1 you get 2 bone dragons from the fallen stack, which is enough. You're not counting on the raised undead to win the battle for you - just to stop the crystal from summoning.
The silver rapier helps a lot here with it's 30% attack vs. undead and it's a rather common item. Good matches for this battle are: horsemen vs. black knights (good resistance) and demons vs. everything else. The priests and inquisitors help to drop the enemy stacks to non-lethal sizes and the battle is won
After everything is cleared out, poison cloud over the bone dragons, magic spring on them and get resurrecting. I left the poison cloud at lvl 1 (doing 20-40 poison damage for 10 attacks) and the bone dragons were taking only 3-6 damage from the cloud and giving back a lot of mana. Sweet.
There is one word of caution here. If you're going for the no losses win, you should be extra careful. If you lose a stack, as I did, and the crystal summons something from it, as it happened in my battle, it counts as a loss of the entire stack. That's how my losses count went up a whopping 432 up
