Sam went to the workshop and first time ever, he was without any surveillance and that is because, the artisans don't like their methods being watched by others, so they have this special privilege.
He locked the door and entered the workshop and once again checking the room for any type of surveillance just to make sure, he finally puked out the divine dimension which has been in his stomach.
He learned that he couldn't enter the divine dimension while it was in his stomach, so he didn't access this at all.
Even the blueprints he gave to Rana are taken out with great difficulty after moving the crystal to his mouth without letting it out completely.
The first thing Sam did after taking out the divine dimension is entering it and taking a swig of the heavenly wine. He missed this wine so much and had to cover up the craving with the normal liquor.
