So, what you're asking me is to help you get turnt.
That's fair, I respect that.
There's a spell I know, I never had a reason to cast it before but I'm confident in my skills. It temporarily alters a person's physiology, and I think it will do the trick. Does that sound good to you?
I have to bring up that technically speaking, in the United States you're still considered a minor, below the drinking age. However, we're NOT in the United States. Hell, in Mexico you can drink at 18, and in the United Kingdom 16 or 17 if you're accompanied by a legal adult, depending where in the U.K.
I'm saying this to acknowledge the complications that living in Derleth has, and absolving myself of any bullshit objections that may come up. If anybody comes up to you to complain, send them to me.
