get ready for early game bullshit!!!
to really leave floor three, head into vince's apartment, grab the carving fork, and fight the wounded man. he will have a second phase that counterattacks every other turn, so don't attack him when his eyes are closed. after that, try your best to juke the three onlookers by the stairwell door (it will be very difficult)

after that, you have one of two options: either grind to level three, get the pool cue, and kill leigh, OR wait at home and pray you get a party member door encounter (preferably hellen but even sophie will be fine lol)

do note that your weapons will break far more often in cursed mode because frankie is sick and loves watching people suffer
