Did an (almost) full run of the Delkfutt Tower zones, GoV did not add any new mobs to kill.
All pages (Lower:5, Middle: 3, Upper:5) are around lvl 30~35, except for pages 2-5 in Upper, where you take on a selection of 4 kinds of gigas, bats and arcana. (I exited at 12th floor book, since nothing there was high enough to give Seasoning Stone drop.) Oh, and I killed Autarch as PUP/THF 95 with Mk2 soulsoother, new puppet AI is INSANE

So no worries about ACP run being compromised, it's actually easier with all those books giving RR, Sneak and Invis
