Yep, same problem, haven't had any problems with 'TuRn LiMiT' or difficulty, but this stage was a massive yikes, only way i got through it was a suicide charge with a Dark mage using the spell that reduces Phys Resist by 5(you only need to take out Kaspar not Fontaine or Eris), and even then Eden was the only one left standing, i think i saw one of the developers taking about rebalancing the Behemoth stage so hopefully, they are looking at rebalancing the second half of the game. I'm unable to progress or continue playing the game even until then :s No idea why this one is giving me such a hard time.

If anyone has any insight on how to finish it, please share. This one however, I've tried a dozen times and cannot for the life of me see how I'm supposed to accomplish the objective. I have never died/failed a mission once since this chapter, and I've completed most, if not all, in excellent time. This doesn't give you enough time to take on the three 'leaders' with their stacking buffs. I'm not sure how it's supposed to help or make the encounter slightly easier, as the 'diversion' summons some 'reinforcements' which get annihilated in a single enemy turn, and kills one of your much needed character units. The initial ploy in the beginning is also useless seemingly. and I haven't been able to get one of them down to at least half health before one of the enemy priests heals them back to full, let alone all three, one of which is also the target objective. Combine this with the most enemies I've seen on screen at one time and put them in a close quarters map. the three 'Leader' type units all have two traits, one which halves all damage received, and the other, grants them another 40% damage reduction if there is an ally within 6 tiles. I'll try not to spoil anything, but the enemies in this chapter are seemingly impossible to kill. Hey, Has anyone made it to Chapter 18 yet and have a ridiculously hard time clearing it?
