1. I mentioned aggro-ed bosses. Did this Death spawn when you were fighting Gorecyclops/Lich or  spawned when they were simply "roaming" ?

BTW This event when I've had Death in Bloodless Stockade was my first visit there. I travelled the place back and forth but an Elder ogre spawned only after I banished Death, and it was immediately after like it was holding back (similar happened at Fortress of Rememebrance, also at the first visit) so, I guess it may be deemed a special case where mandatory/scripted Death spawn prevents other necrophage from spawning.

But there is still a problem of Midnight Helix: confirmed 100%, the necrophage won't spawn if I am engaging Gorecyclops/Frostwyrm.

2. I should probably update on my dragon vs dragon boss match...it appears to be a setup. They don't harm eachother :(  Luckily I got those Hellhounds around - just has to "store them in safety" or they'll vanish/get slayed by the Cursed Dragon.

PS You are talking about PS3 version, right? I wonder if PC and console releases differ in some parts...
