Just hit level 11, started Macguffin quest
Finished Giant's Castle
Got everything I needed from the Hole in the Sky
Made a Digital Key
Collected and identified all the Dungeons of Doom potions
Unlocked Haunted Gallery, Belowdecks, Hidden City, and Spookyraven Cellar
Completed Daily Dungeon run
Stubbornly ran the Sombrero for most of the day
Spent adventures between Council quests cleaning up future necessities (mainly unlocking areas)
Completed Council quests as they became available
Completed a bounty at the Airship - Score!
This day was mostly about preparing for the future and hitting level 11; not a whole lot to be improved there.
Run the Gnome any time that I need a drops (pixels, potions, Giant's Castle, Hole in the Sky, etc.)
Powerlevel after completing all future preparations
Finished the Macguffin quest
Finished the war, completing 4 sidequests, with just 3 adventures remaining
Used Gnome while in Spookyraven Cellar, Palindome, and Oasis
Picked up a mojo filter in Oasis, allowing a second Astral Energy Drink
Hit the Gallery to reach level 12
Took nearly 20 adventures to get GMoB, but other sidequests went quickly
Finished the war 9 Muscle away from level 13
None, this day went about as well as possible, save for the RNG
Finished the run 50 adventures into day 5
The lair was just the lair, standard fare
So, I missed the 4-day goal by 50 adventures. I think this run was representative of most, as the RNG wasn't particularly bad or good overall.
For the next run (which won't happen for a while, as the next challenge path should appear tomorrow), I should be able to shave a few turns off by using the Gnome more vigorously at various points (when going for the Friar's quest, Dungeons of Doom potions, and the Giant's Castle, most notably). The place with most room for improvement is definitely the level 9 quest - my plan is to construct the bridge and complete Oil Peak at level 9, but then wait until level 11 to complete the other parts. That way I'll have access to a Can of Black Paint for extra elemental resistance to make the other peaks easier.
There's definitely some room for improvement, but I'm still pretty proud of my 967-turn HC ZM run (my best one yet!).
