A tip for anyone doing solo Daimon runs using Bloodlust/Autonomy: Sleep till nightfall at Gran Soren > ferrystone back to BBI > run/sprint through all areas/enemies > kill Daimon, get loot > leave and deposit stuff with Olra > immediately run through again.
I use a Ranger, with Revenant Wail and Framae Blades. Each go, I only need 5 Large Mushrooms, 1 Tagilus' Miracle, and 1 Conqueror's Periapt to beat him (or 2 of either). The entire run takes just about 10 minutes and you can kill him twice before nightfall is over and you lose the augment bonuses.
If you don't have the Revenant Wail / Framae Blades, just pop more periapts -- you can buy tons from Fournival.
Again, if anyone finds a chest with Dragon's Pain in it on BBI, let me know. Even Dragonforged, my Bardiche Daggers are showing their age at this point and the Chilling Razors I got from Lv.1 Bitterblack Weapon aren't much better. I really, REALLY don't want to have to go all the way through the main game for an upgrade on them when pretty much every other weapon type has popped up.
If you're still looking for Dragon's Pain go to the 2nd stratum, in the area with the door to the safe area -- the big, square stair case room. Usually has Sulfur Saurians in it -- there is a chest behind a bunch of boxes and an oil pot that drops Dragon's Pain, they showed up in there today.
I think Dragon's Vein are now more powerful than Pain, though.
So you didn't notice new/different quests between NG+/post-dragon?
I've only found one BBI Notice Board Quest that isn't available post-dragon: you have to destroy a Silver and Gold Knight at the Everfall (where you fist encounter the tentacles).
Anyone know how many days you need to sleep in grand soren to get BBI chests to spawn? 7 or 1 or?
Some chests respawn after 3 days, some after 7. So far, only the chests in the area around Olra, are the ones to take 7.
