I wonder is it possible to be a slaver without making Robin leave--I know if I make Robin stay home he won't notice me being a slave, but I fear there may be a future point where there's a forced leave
Same, that's why I always keep the save separated or a copy of it whenever I try the slaver route.. I am also afraid that I'll make a mistake and accidentally make him leave :P
As long as you do not take him while you do slaver stuff, he will never leave. No crpg companion 'oh I know you did bad even though I couldn't have found out' bullshit.
