Designed as a foolproof means of ensuring absolute loyalty, even from those ordinarily immune to compulsion and mind-affecting magic, this rune is infused with a single specific prohibition when first inscribed. This prohibition must be stated in 10 words or fewer and the bearer must agree to it of his own free will. From then on, if the bearer breaks this prohibition, he is afflicted with searing pain, taking a –4 penalty on attack rolls, skill checks, and ability checks for as long as he is in violation of the prohibition and for 5 minutes thereafter. This rune affects any creature who agrees to bear it.
