You're closing in on the end game,
@OsaX Nymloth !
My main character was a halfling so I wanted to romance Linzi. They made a nice pair, doing their little jigs from time to time. (Not like those SSSLUUUUUUUUUUPPPPING humans!) Alas, it wasn't to be.
You can take those massive wads of cash, dump them into your kingdom, and buy a bunch more buildings to prop up weak kingdom stats. You should be getting close to... uhhh... whatever it is that lets you train your advisors in half the time, too, which is a huge help. (Not avoiding spoilers there, I just don't remember how that ability came to be.)
That was also about the time I started running into some weird rewards for diplomacy. You always get xp in this game for doing skill-based stuff like lock picking but I got one lucky roll for diplomacy that gave me over a level's worth of xp! A few more followed, too. My lagging main character suddenly caught up to Nok Nok's level! I'm still not sure if that was really intended.
