Yet Another Stupid Death
Yet Another Stupid Death (commonly abbreviated as YASD) is used when a player has done something, usually avoidable, that leads to his or her demise. Originated in NetHack.
It is often caused by hubris - an overestimation of one's player skill or character strength.
Preventing Hubris
It is very easy to gain hubris, or overconfidence, due to Crawl's gameplay loop. By the mid-game, you will constantly encounter, and subsequently mow down, enemies who are trivial to fight. This encourages you to play fast, this makes players feel strong. And for a while, mindlessly autoexploring and autofighting does work. But it's only a matter of time before bad RNG kicks in, or you see a monster that's too difficult. If (and only if) you continue to autofight, you will die.
A common advice is to "play slower". This can work - and often does - but not without caveats. If you play slower without knowing why you are playing slower, you've done nothing productive. Also, playing slower can make you impatient down the line, causing the opposite effect. Playing slower should be methodical, with 2 goals in mind:
- What can monsters do to you 1 turn, or 2 turns, from now? Can they kill you if they do maximum damage? Think about effects that change your position, any status effects monsters can inflict on you, as well as the max damage you can take. (N.B In the late-game: when fighting many monsters, especially with high AC, the chance of taking max damage is incredibly small. The chance of taking max damage twice, even less likely. Thus you may find it acceptable to continue fighting.)
- What options do you have? If you spot trouble early, you may want an effective-but-cheap option. If you're at 1 HP, you probably want to use a scroll of blinking.
Also, you may want to adjust your rcfile. If you make autofight slower, you may catch mistakes you otherwise would've missed. There are two options of note: autofight_stop = X, which is the % HP where autofight cannot be used, and autofight_warning = X, a delay (in milliseconds) between autofight commands.
One way experienced players avoid YASD... is experience. More specifically, the experience in "knowing what and what isn't a threat". A player might autoexplore, find a D:4 ogre, and think "D:4 ogre? That's too risky to fight - it can do 37-39 damage per turn, enough to kill me in two hits". By constantly iterating this kind of thought process over time, one can play fast and consistently.
Like before, if you play 1000 games and don't learn anything from them, being "experienced" won't be of much help.
- One way to help is to look back at your deaths. If you play online, you might be able to download "ttyrecs" and play them with external software. It is recommended to go turn-by-turn: try to find the moment where you go from "you can always escape (even if you need items)", to "you have a chance of dying, no matter what". Then, go back and see what you could've done a turn before to prevent it, 5 turns before to prevent it, etc.
- Then, apply what you learned. Sounds simple,
