Well I just put up a picture of my most recent kingdom loot I have been doing kingdom for probably a couple years now its a nice little investment so I figured I would tell everyone in sog how it works a little bit
To start off your going to want to do the quests Throne of Miscellania and Royal Trouble to get the 15 workers so you get more loot (Throne for the original 10 workers you can do it with just them but doing Royal Trouble gets you 5 more workers)
It's your kingdom so you don't have to follow my guide exactly but I recommend putting 9 workers on maple and 6 into whatever else it is you want (I normally do 6 on herbs because I like my herb collection but iv done 6 on coal as well) the reason to put 9 workers instead of 10 on maples is because if you put 10 on it instead you don't get as many nests per worker as you could putting your worker on something else instead
To get the most out of your kingdom I recommend getting your favor up to 100% every 2 days or so its quite easy to get there with the fairy rings (the code is cip) I just bring a pickaxe and do the coal right near the fairy teleport which increases your favor by 1% a piece however if you have fremmy boots it raises your % by even more, and every day you lose 1% favor.
I have also heard the best way of profit there is coal and maples but everything I have done there has been profitable anyways usually by about 2x what i put in so its a nice investment
Now for the money...I myself put in 7.5m at a time (that's max cash you can put in at the moment) but that doesn't mean that you have to also..you can put in as much as you want and just because you put in doesn't mean you have to collect when your money runs out you can put more in before you do collect, If I remember correctly I read somewhere that if your cash drops below 750k in kingdom it starts taking less of your money each day (normally is 75k a day) which means your workers will also be gathering less resources for you per day so i suggest trying to put in more then 750k or keeping it above 750k but again it's your money so you can do with it what you like
An alternative to putting cash in your kingdom is that if you have completed the fremmy diaries and wear the lvl 3 boots to "Royal Advisor Grim", (which is also the normal person you talk to about your kingdom)who can be found in the same room as King Vargas on the top floor of there castle on the west side of the island, you can trade him your flatpack furniture for cash into your kingdom
Good Luck to everyone if you have any further questions you can post them or find me in game. I hope to see everyone else in here get some good kingdom loots
