Boiling HF well thats quite an effective method of cleaning out unwanted things from beneath the teeths. That also explains why they are so shiny white. HF dissoziates to H+ and F- and the Fluoride gets build into the teeths, probably with the help from some enzyms which are yielded from the "unwanted" things from the teeths well you know meat and stuff. The left overs from the victims have also some abrehesive impact so the whole process at the end has some astonishing similarities to using a tooth brush together with colgate or elmex.
Never heard about the cheating approach with the button assignment before. There speaks the sophisticated long time wizardry player.
I have no idea how to circumvent such a cheating method without making things utterly boring on the setup side.
If the moder has to threw away design setups, because of possible fancy cheating and therefore looses freedom of creativity then he is stuck in a dead end...honestly I would and did not care too much about cheating approaches, for me it is the responsibility of the player to use the game mechanics as they are intended... unfortunately the game mechanics are in some aspects very poorly designed.
