           was lawful character whose stinking cloud caused a delayed
           killing of a peaceful human, triggering the "murderer"
           penalty while successful prayer was in progress.  It could
           also happen due to inconvenient timing on Friday 13th, but
           the magnitude there (-1) isn't big enough to cause trouble.]
           We don't bother remembering start-of-prayer luck, just make
           sure it's at least -1 so that Luck+2 is big enough to avoid
           a divide by zero crash when generating a random number.  */
