I can't defeat Ruvin at all! I'm currently in Trald's Route, but I already picked all the choices I can find to try and beat Ruvin. It just leads me to a bad end... Are there any hints?
There is a very specific order you have to choose the responses to win, all other variations are a loss. Pay attention to responses that get him hot and bothered without making you give in too much to his dominance.
Try buying drinks from the bar beforehand. During the fight, pick the options that seem like u r in control and not to give in to his lust. Then before the final option, use all the drinks u bought (from the bar only).
