>how much does the goblin flask weight?

One portion of the fluid would be 1 lb.

This lovely flask

weighs .6 lbs and will hold .4 lbs of fluid. Not very efficient, but stylish and functional. Certainly enough to get you started on a night of binge drinking goblin hard meat alcohol. Guarenteed to make you blind, probably.
