Alignment is on a -1000 to 1000 scale, with -1000 to -351 being evil, -350 to
350 being neutral, and 351 to 1000 being good. Your alignment changes according
to actions you take, skills you use, and whom you kill.
Some equipment and skills may be used only by those with a certain alignment.
If you try to use such alignment-restricted equipment, you will automatically
drop it; if your alignment changes, equipment that is no longer usable by
someone of your alignment will zap you and be moved into your inventory.
