KOTC required on the third time I played it i completed the ironaman run because I abused crafting and fireplaces + I started with MAx HP when level up and one 18 stat assured for your characters. (Crafting is just insane in KOTC)
After that I tried to get a run with no crafting and only one use per fireplace (and other rules, you can see here the thread
http://www.heroicfantasygames.com/Forums/viewtopic.php?f=2&t=334). and had my best experience with an RPG ever it took me 16en tries, it was so fun to do each run and I wish i could have so much fun with other RPGS out there.
The key to run in KOTC is 2 clerics, no matter how bad you got shafted in the initiative roll, 2 clerics can get your team back up to fight. The major problem of KOTC are the early game fights when you don´t have OP spells, once you get things like stoneskin, the game becomes quite easy, once you are level 18 and you get dominate monster and true resurrection, it´s almost impossible to lose, the only hard fight at that point is one where you start and a lich stun almost your whole team, then it becomes a race of your clerics brining back your team fast enough, once you manage to have 2 clerics operating, then its gone. If you notice several of my runes ended on the first 1 hour of the game. I place at the bottom the fights that i consider harder and most happen in the first hour of the game, I find that a trend in RPGS.
Im a walking promotion of KOTC because I wish more games were like KOTC. I really had one of the best experiences of my gaming life trying to complete an ironman run with rules in that thread.

Here Trying to recover the fun i had i made a new challenge, right now im on the 5th run and so far failed, as you see this is 2013.... Im not having too much fun because I dont know even if its possible to complete the game with 1 cleric in ironman to be honest and i just replied the game too many times, but Surely i will try again sometime when i have time.
