I've started this path. On buying/using a replica august scepter via the relay browser, KoLmafia didn't recognize that I'd gained the associated skills. A "refresh all" corrected this.
This path recently dropped the Standard restrictions, giving access to a lot of old IotMs that aren't familiar or equipment. KoLmafia seems to be handling this change well, for the most part. However, I am getting some issues from KoLmafia thinking it can pull things it can't. I'm in HC LoL, but the maximizer sometimes suggests free pulling Retrospecs, and scripts think the Clan VIP Lounge key can be free pulled. For both of these, KOL gives the error message:
Only food, booze, potions, combat and usable items may be pulled on this path.
(It's not entirely clear to me what "usable items" means here, since I also get that message when trying to free pull puppet strings, special edition Batfellow comic, and Bastille Battalion control rig.)
I've come across the same issue today in a HC run. Maximizer believes Restrospecs are available as a free pull, but the path doesn't support pulling equipment.
