Groflah is in the bar, and accepts the Tumpy Tonic. He, however, does not give any experience. The faction gains also seems really low.
This used to be a good way to get great XP back in the day. Would take you up several levels fast if you were low (example of said XP gain on alla. "the first couple took me from 1 to 2").
On the faction gains: I gave him 3 stacks, and there is post on Alla about turning in 6 stacks, and going from kos to indiff. I turned in 3 stacks and I am still at indifferent. I remember this taking a bit to get to max ally, but only a couple hundred.
