Let’s talk about the about 2100 quests…2127 or 2129 or something alike, sadly its very unspectacular when you done them all.
Well there is not too much to say about them, but you can make it easier for yourselfe if you visit a new maiden when she is new some times (not random, but paid with gems), cause the cost of this visits is linked to the intimicy of that maiden, so it is cheap at first, but if you do some processions and her intimicy is raised, than it can get pretty expensive and you will need some visits. (If anybody knows the exact amount or can at least tell me it’s above X that would be wonderful)
And yes: You should definily do them, in the end you get > 1000 Exp for some of them, which will help you level up.
