in order to cheese the hammers pet in the secret room on lady vengeance you simply need to pick up all or most boxes and barrels on the ship, you then enter stealth mode on all chars and use the pyramid that you have picked up in her quarters, once in the secret room whilst still in stealth sneak up to the balcony, then simply place the boxes all around your character and stack them on each other "the boxes" once that is done they will attempt to hit you from below so you need to move some items or chests for that aswell its pretty easy to cheese this way. they will hit you with backlash but they wont port whilst doing it , if you dont stack the boxes on each other they will port ontop of the box.
HOPE that helps.
