It appears I did a bit too much CoOp and over-leveled...
I was told by the Emerald Herald that in order for me to open the final progression area, I needed to find four old souls, beat the bosses and light their primal bonfires. At least i think that's what she spouts at the beginning of the game.I had checked the big locked gate a couple times when I was near it, and it was always locked tight. I remembered I had seen an NPC sitting at the crossroads that I hadn't finished talking to, so at one point I decided to quickly pop back over and finish his dialogue to see if he moves or maybe gives me a goody or two. I like goodies. I found him,m chatted him up and he moved on, saying he would meet me in Tseldora. Since I was near the big gate, I dropped by, just to check. It looked different, although I couldn't pinpoint exactly why. I walked up to it, and instead of the "It is Locked" error I had been getting, it opened!
"Wait a second..." says I
I check my inventory and yup - 3 Old Souls. I thought back to the bosses, and was sure I had only encountered 3 primal bonfires so far. What gives? I dislike checking guides and walkthroughs, so i just typed in 'Dark Souls 2 Primal Fire Bosses" in hopes I get as spoiler-free of a list as possible.
"OK...The Rotten...check...Freya...check...The Sinner...check...The Iron King...uh wut."
Who the fak is The Iron King?? The zone says Iron Keep...a zone I had cleared a while back, definitely beating the boss, as I had used that same boss afterward to grind sunlight medals for my covenant... What the heck? That boss was called Smelter Demon, not Iron King. Perplexed, I begrudgingly opened the Iron Keep guide and scanned over ti quickly.
Three Bosses.
THREE!!! Not sure what I missed, but it was hidden well, because I scoured the level for loot and like I said, went back to hang around there and do CoOp with people stuck on the boss.
Doing a bit more reading, I find the issue - From Software tacked a Covenant-driven PVP zone in the middle Iron Keep, called Belfry Sol. When i got to the fire, and figured out it was one of the (optional) PVP dueling areas, I split, not checking to make sure there wasn't anymore PvE content beyond the tower. Whoops!
So, why did the gate open? I over-leveled, according to From Software. Once you reach 1 Million Soul memory (1 million souls spent), the Shrine cracks regardless of Primal Fire progress. I blame the jolly CoOp!
So, since there will probably be loots I missed on the back end of Iron Keep, off I go to finish that! Then, back to Drangleic Castle!
