We are now on the 4th part of the Kingmaker series and are somewhat under-level compared to the suggested level for the module as I understand it. The party consists of me, lvl 9 cleric of Desna, a lvl 8 barbarian, a lvl 8 fighter and a lvl 7 druid. As I understand it the 4th module is for lvl 10-12.
Anyway, we were out strolling and exploring the northern parts of the area west of Greenbelt and came across a barbarian camp in front of a cave. We pondered this a bit and decided upon a night assault by Dimension Door. Everything went very well and we secured the area and freed some women held in a cage.
After resting up I started teleporting the women back to our capital city.
So, after some logistics were done we head into the cave and came face to face with 2 witches which we beat down. Continue on to the left side and after crossing 3 rooms of obstacles (or was it 2) we get to a big room with a huge suit of armor. As we enter the room the armor animates and we are confronted with an Iron Golem. In 2 rounds he has both the barbarian and fighter down to 10-15 hp and my Searing Light spell did zip damage to him due to immunity to magic (I was told by the GM in a "Muahahahaha!" kind of fashion). My own melee output is horrible as I have gone for a Morningstar/Shield aproach in Full Plate for maximum AC (27 AC without spell buffs). At this session the druid was absent so there were only the 3 of us.
Needless to say we run for our lives but made it out. Both the melee guys were in a "We are NOT doing that again" mood.
We start exploring the rest of the dungeon and nothing much happens and the session is over.
Now here comes the part that I have been called out on. I was frustrated by meeting such a dangerous monster that seemed invincible, and its not the first time we have been dissuaded from exploring further in areas by talk of danger and horrible things. Because of this our party isnt very well decked out with magic items. Most of what we have is made by my cleric with the Craft feats (Weapons/Armor, Wondrous Items).
So, in the meantime I do a quick search on Google for "Cleric kill Iron Golem" and I end up in a thread on these forums which explain some strategies that could be used to defeat an Iron Golem (general strategies, not specific for that module). And for the first time ever I am introduced to this wonderful Summon Monster III monster called Lantern Archon. I quickly see the potential to wreck havok on our big murderous foe.
And then this weeks session comes along and I start asking questions. How high was it to the ceiling of the golem room (50 feet). When did it activate (when we stepped into the room). And I then tell him (the GM) straight out that I have researched a bit and found something that looks like a good strategy to use. I explain it to him what I intend to do. As a cleric of Desna I cast Fly spell on myself, then Summon Monster V for 1d4+1 Lantern Archons which I instruct to fly over the golem and pound it from above. Short story shorter, we kill the golem in 3 rounds.
The GM goes dark red and starts pointing his finger at me calling me a cheater. "You cheated!" and "Dont ever do that again!" and "For that you only get half xp for the encounter!". So, we only got half the xp for the golem. I didnt care to argue much. I just pointed out as a lvl 9 cleric which was heavily invested in creating magic items and being the ruler of the kingdom would have access to information back in the city (about 12-15k people living in our city as I understad).
Now, I never engaged the GM in any information research process because I mainly recogniced the information I found to regard the use of the Summon Monster V spell and Lantern Archons specificaly. And I tried to argue that this was mainly about me finding out how I as a cleric could use my spells to the best of my ability. Which fell on deaf ears. Mainly because I had explained that yes, I did search specificaly on the internet for how a cleric can defeat an Iron Golem.
