Availability
It is definitely available pre-hardmode, I got it too. There is the slight problem that I used it though so I don't have it anymore.DanZeMan (talk) 16:25, 24 May 2020 (UTC)

 * You do have a way to show proof. Taking a screenshot would be greatly appreciated, and if you’ve fished up some pre-HM crates as well, then it would be near-concrete as you would have no reason to go to that much effort to fake it. 108.217.54.150 22:04, 21 May 2020 (UTC)

Here's a screenshot I took, this is pre-hardmode and after I just used the book. Caught it while fishing in a blood moon, standing on the surface at that oasis fighting monsters with my shield of cthulu and minion, while I fished. https://i.imgur.com/mQwydUP.png

Took me something like ten Blood Moon fishing trips but I finally got one for myself in pre-Hard Mode. Is there any info about its rarity other than 'green'? Like, 1 in 100 or whatever? https://i.imgur.com/mUZhXJW.png 14.2.104.97 04:25, 26 May 2020 (UTC)
 * Yes! It is a Extremely Rare-quality catch that occurs roughly 1 in 3 successful Extremely Rare catches (i.e. at most 1 in 18 catches, depending on your fishing power), which can only be caught if it has not been used in the current world (see ), and only during a Blood Moon.

Permanent
Are we sure it's permanent? Some evidence would be appreciated. XXfirelXx (talk) 22:01, 21 May 2020 (UTC)


 * Yes - there's a flag in the game code named, which is saved with the world and is never reset. --Eraloiz (talk) 22:08, 21 May 2020 (UTC)

How to tell if already used?
Without resorting to external tools, is there a way to tell if this has already been used? -Jatopian28123 (talk) 11:09, 6 June 2020 (UTC)


 * I'm not sure if it allows this, but probably if another character (from a different world) could bring the item to the world then it couldn't be used (if it had already been used in the world). I'd also imagine you could calculate the damage that the NPCs should be doing with and without it and figure it out that way. Neither solution would be ideal though, but that's all I can think of personally.

 * According to the game code, that's all, yes. You'd probably want to either (a) remember if you [or another player] used it or not, (b) try to fish one up (you won't catch one if it's been used in the world you're in), or (c) get one in a different world and try using it in your world. - Fistsh (talk) 02:09, 7 June 2020 (UTC)

Question about which NPCs this affects (if you don't have them all yet)
Does anyone know if this affects only currently obtained NPCs or if it includes all future NPCs that you don't have yet? I currently have this pre-hardmode but I don't want to use it if it won't affect NPCs I don't have yet. I'd assume it will affect the future NPCs (and NPCs that are "active" but dead upon use), yet I still want to make sure. I also assume if an NPC dies the successor will be affected as well, but technically this isn't explicitly stated. --MatthewTh0 (talk) 00:06, 7 June 2020 (UTC)
 * To quote Eraloiz from a few lines above: "[T]here's a flag in the game code named, which is saved with the world and is never reset." So it affects the world, rather than individual NPCs. Thank you, Eraloiz. :) --94.230.208.147
 * I read that, but I guess my thought process was that the game could technically save a list of alive NPCs when it is used (although I realize that point probably wouldn't have been omitted in hindsight). Anyways, thank you! :) -- MatthewTh0 (talk) 00:49, 7 June 2020 (UTC)
