It would be hard to smuggle this considering it is based on the area effect and they leaves right when you leave the dungeon if you manage to smuggle some teleport into the dungeon so you could teleport out. The only way to keep the effect is if you were to stall it right when you get out. And to use it for pking or something you would have to have some free walk stall to walk around. I believe this is what you would need, although I''m not very well informed on this sort of thing. Although considering that Thok has a high strength level in the saga's if you were able to smuggle the effect out you would probably be more concerned about using the high hitting for pking and less worried about having a cool high HP level.
Another thing that I think would be cool, like determinate mentioned. If you were to get 10k+ life points I wonder what it would look like when the LP's go off the screen.
