Lessons learned the hard way

Lessons learned the hard way was a huge Rodney entry. It was so large that it had to be removed from the database because Rodney would become unresponsive to everyone else whenever someone requested the entry. For a while it was hosted by GreyKnight, but now that the wiki exists we can put it where it really belongs.


 * You have to really be INSIDE a temple for sanctuary to work. The door isn't good enough.
 * Don't eat wraith corpses when satiated. You don't get a warning.
 * Don't wear levitation items until you need them. They deprive you of Elbereth and other useful escapes.
 * If you just spent a year extincting/genociding everything and then polypiling gems, hauling them to the first floor, trying for hours to get your giants arranged around the upstair, and Rodney comes...for the love of God, don't quaff the potion of gain level he may drop on death without checking B/C/U first. Lives have been ruined that way.
 * Levitation spells don't cut it on Medusa's Island. Find a permanent source.
 * Be wary of statues in the Gnomish Mines...
 * Don't bring a pet gremlin to Medusa's level.
 * Don't panic.
 * Don't EVER tangle with Cyclops, the Healer quest nemesis, in melee.
 * Be very careful with uncontrolled teleportitis in stores!
 * Plains centaurs in the mirror are stronger than they appear.
 * Baby silver dragons don't reflect zaps of cold that you shoot at them. Looks like it's going to storm!
 * Hitting e instead of w can be a fatal mistake when you have a cockatrice corpse.
 * Just because you beat Sokoban and got a bag of holding, it doesn't mean you're invincible.
 * Remember, "Thou shalt not worship graven images"
 * Never sacrifice something you can't touch! Attempting to lure a cockatrice onto an altar for sacrifice with the idea that you can do so without touching it will cause you to develop a stony appearance without any chance of eating a lizard :(
 * Never eat tins in shops whilst wielding potentially expensive artifacts.
 * Using waterwalking boots on the plane of water will result in you drowning. Levitation, on the other hand, will work safely.
 * Always use up cockatrice eggs you lay. Tame cockatrices turn any golem to stone golem, which is hard to kill.
 * Cursed athame isn't good item to engrave with.
 * Don't carry wands/scrolls/potions outside bags. Nothing like standing on the vibrating square with the Bell of Opening (0:0), complaining about exploding wand of cancellation and wand of wishing and not having a scroll of charging handy.
 * Don't rely on your quest artifact as the only source of ANYTHING.
 * Don't stand on ice when there are foes with fire attack around.
 * Don't try to disarm/disarmor your Archon with F command when polymorphed into a nymph. You can untame it.
 * Ice box isn't good place to keep your potions in.
 * If you have crappy ISP, NEVER reconnect to server right after you got your internet connection back. There can still be some glitches with it.
 * NetHack doesn't know about arrows/function/home/end/page up/page down keys and treats them as escape. Therefore DON'T TRY TO EDIT YOUR WISHES WITH THEM.
 * NEVER have potion stack directly on altar when there are intelligent foes. Wand of striking == BOOM!
 * NEVER skip messages with space. Ever. Especially when handling petrifying monsters.
 * What do you think amulet of life saving is for?
 * When polypiling, be careful with where you aim. In particular, don't hit that damn chest with goodies - if it polymorphs into non-container, ALL CONTENTS ARE LOST.
 * When you have laggy connection, NEVER type next command before you see how previous one ended.
 * When running from a nasty monster, go back the way you came.
 * Be careful of what items are marked as 'y' and 'n' in your inventory to avoid confusion with yes/no prompts. For example, trying to eat something on the ground while levitating by typing 'ey' quickly will have disasterous effects if your inventory contains 'y - a cockatrice corpse'.
 * When hiding in a shop to recover HP, make sure to rest instead of search to avoid finding (and waking) mimics.
 * When breaking wands for its area-denial purpose, DO NOT break a wand of lightning unless you hate your rings.
 * Make sure comestibles (esp. rubber chickens) aren't assigned 'e', wands aren't assigned 'z' or 'a', potions aren't assigned 'q', scrolls and spellbooks aren't assigned 'r', tools aren't assigned 'a', weapons that might be cursed aren't assigned 'w', armor that might be cursed isn't assigned 'W', rings that might be cursed aren't assigned 'P', etc.
 * Wield the cockatrice corpse when you're already in position to attack (you won't be moving into any unknown squares). Otherwise you will fall into a spiked pit on your way to your victim.
 * When the ground around you looks the same except for being a different color, examine it with / or ; before stepping there.
 * Don't anger your god after getting divine protection. Praying for unholy water on a crossaligned altar, for example.
 * Don't go below dungeon level 18 or so without a means of crossing water. Falling past Medusa through a hole can really ruin your whole day.
 * Don't melee cockatrices if you're polymorphed, especially if you are a vrock, master mind flayer, vampire lord, dragon or any other biting monster.
 * Don't try to polymorph a merely annoying monster just to get it out of your way; save your charges (or mana) for things that are just about to kill you; the creature it becomes might be something deadly. (StormEagle, blue jelly => ice devil)
 * Drop your gold, bag of holding, and unicorn horn on another square before ting on a throne.
 * If you find Minetown bones, before you go #chatting up the priest, make SURE both the priest and the altar are of the same alignment.
 * If you have no gloves and have recently dispatched a cockatrice, always move with the 'm' key. Doing so will cause you not to automatically feel objects on the ground.
 * If you levelport, angry shopkeepers are somehow able to levelport with you.
 * There is a vital difference between ' is displeased' due to praying too soon, and praying on the wrong altar or with negative luck/alignment. Only the first one makes your god angry.
 * Any monster in the 'follower' category will follow you through portals created by the Eye of the Aethiopica.
 * If you are being held/crushed by an owlbear, zapping down with a wand of digging is not as effective as you might think. Engrave Elbereth with it instead...
 * If you leave skeleton keys (but not lock picks or credit cards) lying around, monsters that can open doors are smart enough to pick them up and unlock doors with them.
 * If a fountain in Minetown reduces to a trickle, cease using it immediately.
 * For beginners: if your HP shows as yellow or red (with the HPcolors patch), you have the spell of healing and you have enough power to cast it, do so. You'll never know which gnome has the wand of lightning/cold/fire.
 * If someone throws an egg at you, it might have been a cockatrice egg - don't skip through the messages about stiffening and turning to stone as if they were ordinary battle spam, if you don't want to become a statue.
 * If you don't have a way to protect against touch of death, NEVER step off of an E-square when facing an arch-lich.
 * If you're trying for #conduct weaponless, just leave pick-axes on the ground. Don't even bother to put them in your BoH. Use wands of digging instead (which are not wielded). If you're going for #conduct pacifist, wield a cream pie and never let go. Rely on 5 to move.
 * Never underestimate a bones level.
 * While trying to tame something using charm monster that can resist, you'll probably gain a lot of pets. Naming them *all* will help keep you from sacrificing a pet (since corpses retain names) and losing your 50 points of protection.
 * Get a second or third opinion. ALWAYS.
