Talk:Scroll of amnesia

A scroll of amnesia makes you forget spells too, right? 88.112.19.225 00:14, 13 September 2008 (UTC)

Who is this Maud person anyway?

Just wondering... -- 86.152.193.91 16:53, 19 April 2009 (UTC)

• See the Encyclopaedia entry in the article. It's from a fairly famous poem by a fairly famous poet... -- Kalon 00:12, 20 April 2009 (UTC)
  • I'd heard of the poet, but had never heard of the poem before NetHack. --Kahran042 01:44, 22 April 2009 (UTC)
• That never even occured to me. I am shamed. Lord NAg 23:11, 21 April 2009 (UTC)

What does a blessed one do? The chart doesn't have an entry for it.

blessed un-confused is included in "cursed or not confused", therefore you forget all of the current level, on top of forgetting object identites. -Tjr 15:10, November 21, 2009 (UTC)

"... forget whether you are punished ..."

What exactly does that mean? Does your character forget it has an iron ball chained to him/herself? That doesn't seem like something you could forget, as you'd immediately notice it once you started walking again. Or did they mean your God's anger? Could someone explain what that bit means? -- Qazmlpok 23:13, December 6, 2009 (UTC)

I combed through read.c and ball.c to figure this one out and all I can conclude is that this is a TDTTOE. It only affects one bit mask - u.bc_felt - that acts when one uses look on a square with the ball or chain or tries to move the ball or chain. Being able to forget that one was punished only matters to an amnesiac blind punished player. Yes, first you have to be blind and punished and then you have to, somehow, read a Scroll of amnesia. Since it's impossible to read-test scrolls while blind, you have to already know the scroll you're reading is amnesia. The whole matter makes a little more sense after reading the ball.c source which likens handling the ball and chain to "messing with the hero's mind." --FJH 19:49, 23 November 2010 (UTC)

You have a sense of deja vu.

What does this message mean?
I had this message appear in my last game, and I think it means you went back to a level you forgot from amnesia, but I'm not sure. I searched it and it didn't appear in any of the 3.4.3 source files here, so I'm confused. --Uncreative Username 15:53, May 28, 2010 (UTC)

I agree, that's what the message means. --Ablotial 20:37, 9 March 2011 (UTC)

Randomness after Amnesia?

During my last game, I got amnesia from a mindflayer attack and forgot some of the things I once knew. I had a glass wand that I knew was teleportation and had named them as such even though the game didn't auto-identify it (I guess because the objects weren't teleported somewhere I could see them, so it was possible they went invisible or something else, except I had see-invisible so that wasn't it). Anyway, after the amnesia, I had "forgotten" the name of the glass wand. I re-zapped it and discovered that it was STILL teleportation. Was that a random happening of it being re-assigned to the same thing, or does it actually not re-randomize things? In other words, if I wrote down on a piece of paper all my discoveries, would amnesia be irrelevant (though still annoying)? --Ablotial 20:37, 9 March 2011 (UTC)

Amnesia does not re-randomize appearances. You can write down appearances like that; it's possible, tedious, and also is a form of metagaming. -- Qazmlpok 20:44, 9 March 2011 (UTC)

vibrating square

If you map the last level of Gehennom, you may use this to aid you in finding vibrating square in case you have a hard time memorizing your patterns. --178.36.196.132 20:08, 31 December 2014 (UTC)Winhert

25% or 24%?

The scroll code calls rn2(25) for percentage of levels to forget, and the maximum value of rn2(25) is 24, not 25. However, forget_levels calculates ((count * percent) + 50) / 100. The +50 boosts the percentage. For example, if count=20 and percent=24, then ((20 * 24) + 50) / 100 = 530 / 100 = 5. 5 out of 20 is 25%, more than 24%.

Worst case is count=3, percent=24. ((3 * 24) + 50) / 100 = 124 / 100 = 1. 1 out of 3 is more than 33%.

Sokoban also raises percentage if count > 50.

I don't know how to make the article both correct and simple enough to be useful. Perhaps just drop the percentages. But then someone is likely to put wrong percentages in again. The old version said 1% to 24%, and both the 1% and the 24% were wrong.

I think it might be best to get as much of the necessary/pertinent details in, and then pare it down/simplify as needed ASAP. For this scenario specifically, I think we can swing a bit of <math></math> - it may or may not be avoidable, but that's a bridge we likely cross when we come to it. I'm also open to other ideas on that front. --Umbire the Phantom (talk) 09:00, 5 June 2024 (UTC)

Circling back around after several minutes of thought, my guess is the 50 in that equation is a form of rounding, given that it tends to push anything under a half up to the next integer - I'm not 100% on that though, and I'm also not great at actually constructing equations specifically using the math markup (which has always eluded me tbh) to better represent this visually, though I might be able to find someone who can. --Umbire the Phantom (talk) 09:53, 5 June 2024 (UTC)

Sandboxed a draft both to work on later (it is 6am) and to try out things relatively free of consequence. --Umbire the Phantom (talk) 10:21, 5 June 2024 (UTC)
