This is an achievement received for fishing. That's all there is to it. After you get past a certain point in the game, you unlock a playable character that has the option to fish while standing next to a body of water. You know where you are able to fish because the water sparkles. While fishing, if you press the interact key when an exclamation mark pops up, then you will catch a fish. It's fairly simple, and there's no reason for you to not have this achievement. Now, you might be wondering: "Why is this achievement description so long? All of the other achievement descriptions are much shorter than this." Good question. Here's some food for thought: why does it matter? What if I just feel like making one of the Steam achievement descriptions for my game comically longer than the others? Maybe I'm just testing how long I can make the achievement description text to see what the character limit is. If you are reading this, then congrats. I don't imagine many people will be doing exactly what you are doing at this very second, so at least you're special. Did you know that there are 5 different types of fish that you can catch in Roseblight? There's an NPC that will buy them from you, so you can make some easy gems. Fun fact: that NPC is also a fish. Pretty crazy, huh? A fish buying fish. What a strange world Ahokau is. Are you seriously still reading this? You know, with the amount of time you've spending reading this achievement description, you could've been playing Roseblight instead. You could've been experiencing the magic of the fishing minigame yourself instead of having the game's developer explain it for you. What a shame.
