OK, so, looking ahead to "A History of Ashes" in my campaign (we just started "Seven Days to the Grave"), I like the fact that Paizo have put in more content - but Deathhead Vault seems to really break the flow of the campaign. It's like, "go and find the long-lost magical sword that is the only thing that can stop Ileosa! But wait, there's a detour you have to take all the way back to Korvosa first".
I was considering just shunting it wholesale to the beginning of "Crown of Fangs" (XP won't be a problem, considering I use milestones rather than counting it). Yes, the party will have Serithtial at that point, and they will be a couple levels higher than recommended, so they may end up tearing through the Mantis and the Maidens like Laori's chain through her impractical outfit, but maybe after the horrors of Scarwall it'll boost their morale to strike such an easy, crushing blow against the Queen's tyranny? Before I go hurling the rest of the chapter at them, anyway.
What do you guys think?
