MY tips and tricks are :
- Happiness is key
- Say yes to almost everyone EXCEPT the Vampire and the jester (Like dude, 700 gold for 25 happiness? I'M NO FOOL)
To be precise, he gives 25 happiness immediately and more later. So it COULD be worth it, but usually you don't want to.
Oh really?
Cause personally he gave me happiness once I think and then he almost immediately asks for more money.
In my experience, he keeps giving happiness at the phase after the questions are asked each day but before the stats are showed.
