if you enter the order mission Down the Hatch with a partner, the one who isn’t doing the drinking gets 3 skills, “Cheer!”, “Boo!”, and “Throw Refreshment”, all of which are broken.
“Cheer!” is supposed to, according to description give your ally might, but ends up giving it the the enemy as well.
“Boo!” is supposed to apply vulnerability to the enemy, which it does not.
and “Throw Refreshment” is an AOE heal ability that applies to both participants even if only one is targeted.
These skills are only for the drinking game at the beginning of the instance.
