"Less spoilery guide" link in my signature has some tips.Oh.....any tips for me just started the game. also when is the 18+ scene. was there any updates for Yona pregnancy
18+ scene is whenever you start it. Use R button as male MC for enemies, and talk to friendlies (you'll need them to like you on the level of 50 or above).
And if you play as female MC (Yona), you get rape on defeat and rape when you're down. Don't worry, you're immortal.
As another comment has said, Yona still can't get pregnant.
