Currently, there is a bug with freezing, which can disable the Babbling Book indefinitely, but I think it shouldn’t be that necessary. The party I’ve used is something like this: Khadgar, Nemsy, Balinda, Malchezaar, Xyrella (or whatever merc with Holy abilities) and Bwonsamdi — yes, the bouncing strategy. I don’t rightly remember the details of how I’ve done it with this one, but I think starting with Malchezaar first is advantageous because of his battlecry, and Balinda is necessary. You can do a few bounces, bringing up multiple water elementals and doing Fire and Frost with Balinda… The bug, however, does prevent a ‘Prideful Wish’, otherwise something else (Diablo with a slowing effect, maybe?) would be needed.
I’ve done it without Balinda, though, on my first attempt (was it Lokholar instead of her for climbing?), with a bit of bouncing and some randomness on my side.
PS A bit off-topic, but…
If you call that ‘free press’, then… Well, no matter.
