1st enslave val during your 2nd conversation with confusion and suppression or my personal favorite use grapple on her when she is crying about the leg warmers, 2nd julia cast confusion and suppersion or again cast grapple, 3rd cassandra beat her in battle then cast grapple or during the battle keep casting boost then when she wants you to fix her cast suppersion dumb bitch just lets it happen, 4th after your first conversation lesson with jane talk to sarah again so she goes to your room cast the stone skin spell after that cast boost then cast suppression on her the reason you do it this way is so you can actually enslave ashley after this get sarah to lvl 11 then do the sarahs home plotline and enslave her mother,5th if your about to die and you get saved by resuce girl talk to her outside the school then to into the dungeon and wait a while after that you will get another cut secene of girl in a fight dont help her when dan says she looks ruffed up cast suppression then talk to her in the hallway after that she will be your slave ,6th do the Berserker quest line until you get the book after that do the rest of janes lessons until you get to the transform spell you can either do it normally or turn into jane after a while go back and talk to julia get the cut secene where she wants you to talk to get jane to help her sister do that secene then after a while you will get a cut secene of julia saying she fixed ashley you know which one unless you havent done it yet which then i recommend the new walkthrough https://changermcgame.blogspot.com/p/introduction-game-can-be-fairly-non.html?zx... , when ashley is back to normal you can release her if you wish or tell julia to fuck off either way it doesnt matter becuase ashley can not fight back against the suppression spell at all, next i recomment getting molly fired so you start the Derrick family plotline and during the meeting cast conversaion instead of suppression on her black mail her then give her the book next time you talk to her in the item shop get her and her son, then i reccommend getting ms rack talk to her get the conversation with her talking to you about vals behavior then talk to julia get info on her then back in your room talk to val twice so you get ms rack to come over, after that do the cassandra/sarah backstory plotline, then have normal julia in your party and go into the enchantment shop or whatever the hell its called ask the women about her ears and julia will call bullshit on her entire story agree to help her then go into the libary and throw a magic charm at her then talk to her back in your room, then ima be honest i never have a clue when this one happens when dr tiff frees val from your control talk to julia then talk to mr rack then talk to dr tiff to enslave her then after you leave the room talk to val in the hallway and cast confusion on her, after that do the whole monster tamer thing finish the first misson then in the conversation for the second say the 1st oppion not the second after you finish that misson the girl during the monster quest place will ask if you want to see her collection say yes and during the conversation in the back room ask about the charms then tell her about your magic after that when she says she is avoiding the conversation or whatever cast flirt go to your room and suppress her or grapple her (if there are more i do not remember) at this point in time if i missed some tell me and i will tell you how to get them
