One of the quick leveling mechanics I found – was giving yourself to the goblins at the starting sewers...
Despite gangraping her 2 times a day, and making her give births... Believe it or not, they're FEEDING her and make sure her HEALTH was on an okay level. So you literally can survive with them for infinite amounts of time. 😉
I tried that couple times, starting the game at about level 40. 😂
Only con is, Lona would have completely stretched out orfices, which would take a pretty penny to fix at Elise. 😊
