A couple of drops of sleepy time in the flask and .... woops! I dropped the whole thing in... hmmmm... well, I guess it'll have to do. Right?
Ready to bring our little concoction to the good general? All you have to do is find the general, give her the flask, and talk to her untill she falls asleep, then, once she is asleep, swap the sword nearby with this one, it's the duplicate that we made. Then high tail it back to me.
