black lotus can be found all over Mooshu. You have a better chance of finding them early, before the realms start getting populated. If you check near the bosses' houses you can find them there. I know they are a lot in the Cave of Solitude. The earlier you are on, the more likely you are to find them.
Same here! I posted a topic like this, I tried all the dead-ends where boss houses are and no luck. I only found 1 black lotus.
OK -- here is my favorite black lotus run. I'll describe it in detail for those who snuck into Mooshu before they even finished Marleybone (like my Fire wizard did.)
From Mooshu commons (where the shoppes are), go West to the war-torn Hametsu village. Take the left exit from Hametsu village to the Tatakai outpost.
Explore Tatakai to activate all of the jump gates.
The Black Lotus -- when they can be found -- are to the left and right of houses, not just the ones at the cul-de-sacs. You will find some Lotus quite close to the warp gates.
You can construct a route that involves switching realms about every minute. My route takes a little-bit longer, but hits more houses:
From the hub, warp through the blue gate, and walk/fly right to the cul-de-sac, harvest lotus if you find them, switch realms. Harvest again, walk back to the blue gate, warp to the hub. "Peek" at the green road by warping through the green gate, harvest, warp right back to the hub, and warp to the yellow gate and harvest.
Each time you warp or switching realms, you should wait a second before looking on both sides of the house. Either I have hit the new realm right when a new one spawned, or there is sometimes a slight delay in transmitting information that a Lotus is there.
From the yellow gate, you can either:
(1) walk to the next house, turn right to the next cul-de-sac, harvest, switch realms and start walking back to the gate, warp to the hub, peek at the green cul-de-sac again, and repeat the whole cycle
(2) warp back to the hub, warp to the blue gate, and walk LEFT to find the cul-de-sac on the right in the blue world. Switch realms, harvest, and head back for the blue gate, warp to the hub. Peek at the yellow and green cul-de-sacs again, then repeat the whole cycle.
Both routes end up hitting the same number of houses. If you find yourself frustrated at the lack of Black Lotus on the yellow road, you can keep walking the entire path of the blue road. If I like the harvest at the yellow cul-de-sac, I will walk the entire road. You can even walk the green road -- it may not have as many houses per unit of time, but it might yield more Lotus during busy times as the road less traveled.
I set up a similar walk in the Ancient Burial Grounds, where there is a very short walk from cul-de-sac to cul-de-sac, but keep peeking at the other gates in the middle.
I've found EASILY over 20. Go into MooShu, and go into like Hamestu Village, Tatataki Outpost etc: and go to where there are some boss battles, and look behind little barrels/carts. There are some there. Or in Jade Palace, look by the Pagoda. They are some there!
