"Killer" Dungeons. Advice for Players (part 1)

A "killer" dungeon is one that is written with the goal in mind of being difficult for characters to survive.  Characters that make bad decisions or do not cooperate well, are particularly vulnerable to such dungeons.  Killer dungeons are often a combination of powerful monsters, dangerous obstacles and deadly traps.  Killer dungeons can be published or unpublished.  Better killer dungeons reward good decision-makers and do not rely too heavily on the "save or die" saving throw rules from earlier editions of Dungeons and Dragons.

How to survive (win) a "killer" dungeon:

• If the dungeon does not have a time limit, take your time and move cautiously
• If there is no time limit, resting after every fight if possible to make sure that your group is at full strength, can be very useful
• If there is a time limit, move quickly and decisively
• Beware of dead ends
• A little paranoia goes a long way
• 85% of the encounters are logical.  15% are surprises that even the best-prepared party will have trouble with
• As long as you pay attention and think clearly, logical encounters will not be extra difficult. 
• High locations (particularly those without safety railings) and water locations are inherently dangerous
• Teamwork is important.  Characters should work together well and protect each other.
• Have a strategy for retreating that can be employed when most characters are still standing.  Most of the party is in big trouble in a disorganized retreat
• Having pre-determined strategies to use for particular kinds of battles can help with coordination and teamwork
• Scrolls with restorative spells and healing potions are a must
• Although First Edition modules in particular have a reputation for being the sort where everything in sight is to be killed, most intelligent monsters are willing to parley or are open to bribery in exchange for temporary safe passage.  Sometimes paying off the bridge troll is the smart move rather than using up your strength and spells on a non-essential opponent.
