Iron Flesh/Four Kings question

I've been co-oping Four Kings a lot lately and I have experienced two things that I cannot account for.

1 - I've sometimes gone into the fight with the strategy of casting Iron Flesh. However, about half the time, when I try to cast it, the spell is blacked out. Then maybe a few minutes later after cycling through my spells it'll be cast-able. I have the glove equipped and in use so it's not that. Just curious if anyone has an explanation or has had a similar experience.

2 - This next thing seems to only happen when the summoner dies. So we'll be in the fight and we'll kill say, two kings and then the summoner dies. When the camera backs out there will be three kings, instead of two, all attacking and doing damage. I'm just curious as to whether this is a glitch or if I'm crazy or what. Does anyone share this experience?

Thanks

I can answear number one with that you can't cast stuffs like Iron flesh if you have used the temporaliy curse thing. You need to wait for that to fade out. or, if you have other supportive spells activated. For example, inner strength.

Gotcha on Iron Flesh. Never thought of that. Anyone on for the kings?

I hadn't used a Transient Curse for a while (sprinted through Valley of the Drakes and ran past the ghosts and Dark Wraiths), yet couldn't cast Iron Flesh either. I ended up using Smough's armor (chest piece, legs, and helmet) and 2H my Quelaag's Fury, worked better than having Iron Flesh.

Also, the longer you take in the fight, the more Kings appear. Not a glitch. Even if you killed two, if you take too long on the last two, four can appear. You need to beat them as fast as you can. I messed up my first time and had three down, and the 4th one grabbed me three times, ended up with three surrounding me. The fight is damage based, they keep respawning until their health is drained.

I've had the second part happen to me also. It was a glitch, associated with lag probably. I was taking out the Kings really fast, and the host was in no danger at all, when all of a sudden he was getting massacred by an invisible King. There was nothing at all I could do to help him... We ended up winning, but that part was really close.

The first part is like Kaminari said: you can only have one self-buff (or body buff, not sure what to call it to make myself clear!) active. In your example it was probably because of transient curse. But it's the same thing as: can't have the replenishment miracle active at the same time as power within. I'm not 100% sure on the specifics, but I think you can only have 1 self-buff and 1 weapon buff active at the same time. Where I'm hazy on, is which self-buffs you can use together, and what you can't. I think whatever is gear based (grass crest shield, masks, and rings) will not cancel out your ability to cast a self-buff. Whatever is spell or item-based is limited to 1. So no transient curses and iron flesh. Another example: you couldn't have the invisible body spell and iron flesh active together, but you could have the ring of fog and iron body.

Maybe that's what I had, I might have had some self-buff going that I forgot about, probably so I could rush past the Drakes and Dark Wraiths without a problem. Just when I think I've got this game figured out, there's another little rule I don't know. Going solo I've never had a problem with Four Kings, but it seems to get all glitchy when they're co-oped. Which is weird to me, because the game isn't rendering a detailed background, just character models. I recommend soloing them if possible, but if not it's always good for each character to have iron flesh as a backup.
