Useful tips when going against preternatural evil.

• Don't try to manipulate strange alien weapons while having a dozen of sticks of dynamite strapped to your body.

• Do not try to cast spells that require human sacrifices. In fact, Do not try to cast spells.

• When you've just unearthed a chest containing a necklace and a moldy book, do not put the necklace around your neck as "temporary storage while you grab the book".

• Most monsters cannot be reasoned with, especially gibbering mindless sanity blasting horrors.

• The undead only respect one thing: firepower. And they don't really respect that very much.
  

• Whenever you have a chance to kill innocent people for no good reason, don't.

• Make damned sure you are never the first guy into a room. Nothing good ever happens to that guy.
  

• When warned not to linger in the Hall of Shadows, don't camp there for the night.

• Getting the attention of a Hound of Tindalos is a career-limiting move. Do not stroke the nice doggie.
  

• Move city, become illiterate, disown your entire family, never make any friends, marry a fat woman and open a shoe shop. The only way to die of old age. And for heavens sake, always buy a new build house (as long as it's nowhere near a burial ground).

• Do not taunt Happy Fun Servitor of the Outer Gods with your ineffective Thompson Submachine Gun at close range.

• Magic is bad. Anything beginning with "Call Forth" or "Summon" or "Contact"--very bad. "Call Forth" or "Summon" or "Contact" something by individual name or something very big "Call Forth The Sun" for example, very, VERY bad. Especially when missing pages.

• Just because you have a gun, don't make the mistake of thinking it will do you any good whatsoever.

• If somebody runs past you screaming about "the horror! the horror!", follow them. You can find out why later on.

• Don't shoot until you see the white of its ooze.

• Taking careful aim is just wasting good running-away time. Addendum: Combat eats into valuable running away time.
  

• If you're keeping track of time in combat rounds, you're already dead.

• Believing that dynamite will help should be a mark of insanity.
