The fastest way is to go on to ABD farm arrows and ROKA till you get TW then go on the ABD discord and go to the dio raids on peoples ps and kill dio if you dont get the drops then go to another one. If you get the diary but no camera (or vice versa) you can bank the item you got and use the mask. Once you use the mask you can farm more for the camera (if you didnt already get it) then use it to get STW.
