i play this game for a while now , and cant understand how to earn real money. Like academy job 250/day , prost ring with 8 slaves 700/day .... And i see additional house for slaves for 320k ... i will never get that much with my routine. Any tips, please?
There are two type of actions in this game. Ones are for earning money, others are for gaining skills. Working on a plant or at academy - are for gaining skills. You will be surprised how many skills you can get from working on a plant. From obvious Strength and Stamina to common Charm plus Stealth and surprising Range and Science. Working as professor gives you Int and hardest stat to get - Willpower. Money from these jobs are secondary.
About earning money - above comments about bounty says everything. Also Hunting is a very good source of money early game, and this is one of actions that gives you money and skill simultaneously. It can bring you about 5k per week - very good money until you get access to arena.
Ignore all comments about investments. They bring you about 0.5% money per day. Slightly more later, but not significantly much. If you want to have 2k income - you need to invest about one million. Definitely not an option for starters. There are much more better things in this game to spend on, like armour or implants. Use investments only if you are nowhere to spend.
But most lucrative income are hidden in the name of a game. You are slavemaster after all! You can buy some trashy girl on a market for 600,
rape her until she became mindless doll train her to become an obedient servant and sell her at Dockgrave for 40k+.
