I managed to get a 3 day done, and I'm trying to get another one done just to see if I can. I'm making good progress on the 2nd day, as I'm done the Spookyraven part and I'm done the annoying part of the hidden city - the shamans. I'm also half way to level 12, so maybe I can put off killing bosses until I get there. I already killed Lord Spookyraven, so I guess the rest of them I'd have to save for flyering. So that's the Palindome boss, Ed, and the spirit from the hidden city. I might be able to flyer others if I manage to level up before I finish the level 11 quest. And if I still have flyering to do, I could flyer the junkyard. I'd rather not have to set up bees unless I have to, and that'll be gone in the future anyway. I'm going to have to cut it out of the strategy soon.
(Note: Use some skeletons next time in the hidden city, get +50% combat initiative instead of the buoyant tank because I'd actually use that all the time)
Right now, I'm thinking about getting a snow machine for next time since I do have a garden. However, I still need to balance levelling with speeding up quests, so I might not get one since it would have limited use without an actual Winter Garden. Mostly it would be the snow cleats, and I already have tons of -CF with muffled alone. In the future, I would have brood so it would definitely be no problem. I don't think I'd ever switch to unmuffled because I don't need to boost CF very often and as long as I finish within 3 days I'm pretty happy with runs.
I'm going to try to remember to use the VIP buffs to increase stat gains as much as possible. In general, I'm not using all the resources I have available (mostly because I'm too lazy to be that careful).
