Dialogue[]

UI Quest Quest Description

Kayvan the angler seems to be having some trouble...
(Use Nahida's All Schemes to Know on Kayvan, optional)
Kayvan: (I... I'll definitely catch a big fish...)
(Use Nahida's All Schemes to Know on Helbet, optional)
Helbet: (Mr. Kayvan is actually... quite impressive...)
(Talk to Kayvan)
Helbet: Please, do me a favor! I could really use your help!
Kayvan: No can do. Please go.
Paimon: Whoa, what's with the quarrel?
Kayvan: Hey, outlander, care to help me persuade this lady here?
Kayvan: She came to ask me to salvage some antiques. Has been bugging me all day.
Kayvan: She not only scared away my fish but also wants to keep taking up my time.
Kayvan: Miss, why such a hurry? Trying to rake it in with the antiques?
Helbet: No, Mr. Kayvan. I am Helbet with the Akademiya.
Helbet: The Akademiya found those antiques and I'm responsible for keeping them.
Helbet: But there was an accident on the ship transporting the relics. Some dropped off the ship, floating down the river to the lower reaches.
Kayvan: Then go to a professional salvage team! Why bother a fisherman like me?
Helbet: It takes too long to find a suitable salvage team. I've heard people call you "Supreme Hookshot" and that you fish lost items up from the river nearly every day.
Helbet: And you've been fishing around a lot, so I thought I'd ask you to try casting your rod, see if you could get the relics...
Icon Dialogue Talk You are being desperate...
Icon Dialogue Talk Well, if it's Kayvan who casts the rod...
Kayvan: I cast my rod only to get fish, okay!?
Kayvan: Ahem, Miss Helbet, I feel sorry for what you have been through. But I'm only a fisherman.
Kayvan: I cast my rod to catch fish and fish only.
Paimon: You haven't caught even one fish...
Kayvan: Ahem! I've been training to do that with the pure thought in mind. Never thought about hooking other stuff.
Kayvan: So you'd better find someone else.
Helbet: Eh... Eh?
Helbet: Then... How about this, I won't ask you to hook the relics for me, I just need you to go fishing at another place. What do you say?
Helbet: I'm paying you to catch fish! Please, I'm counting on you!
Kayvan: Ugh... I am a fisherman! A fisherman!
Icon Dialogue Talk It's nice to fish at a new spot.
Icon Dialogue Talk Well, a fisherman hooks this and that.
Helbet: Come on, please help me. I've prepared your payment already.
Kayvan: You guys are incessant... Fine, I guess I'll do that for a change. Where do you want me to fish?
Helbet: Many thanks! Just follow me!
Kayvan: Same as before, Traveler. Please help me find some materials for the baits.
Kayvan: Let me think... I'll be using Mint this time. But it needs to be collected from my usual spot.
Kayvan: I've marked the general area. I'll leave it to you. After you bring the materials, I will go over the payment in detail with you.
Kayvan: Miss Helbet and I are going to the fishing spot first. We'll meet there.
Icon Quest Step Step Description

This time, Kayvan's bait requires one Sunsettia and one spike of Wheat. Plus, he demands another three portions of Mint picked from a particular place...
(Approach the marked area)
Paimon: This is the place Kayvan mentioned. But Paimon doesn't see any special Mint...
Paimon: Wait, there are monsters? Could it be that the Mint is taken by them again? Weird...
Paimon: Whatever. (TravelerTraveler), let's recover the Mint!
(After defeating the Fungi)
(Obtain Special Mint Special Mint ×3)
Paimon: Let Paimon take a look. Hmm... The Mint is intact. Let's go back!
Icon Quest Step Step Description

Bait materials are all ready. Let's take them to Kayvan, and see what he can catch.
(Talk to Helbet, optional)
Helbet: I'm counting on you two. If you find the material, give it to Mr. Kayvan, so he can get to work as soon as possible.
(Talk to Kayvan)
Kayvan: Did you find the materials?
(Submit Sunsettia Sunsettia ×1, Wheat Wheat ×1, and Special Mint Special Mint ×3)
Kayvan: That's pretty quick! Thanks!
Helbet: Please start fishing, or the relics could... I mean the fish...
Kayvan: No rush. I need to feel the flow of the water to ensure I can cast the rod with the peace of mind.
Kayvan: Let's see what big fish lies for me here...
Kayvan prepares the bait and begins fishing.
Kayvan catches a wet package after a long while.
Kayvan: What do I have here...?
Helbet: This is... Let me check!
Helbet: This is it! One of the lost antiques! Unscathed. No aquatic creature has gotten inside...
Helbet: You actually hooked a relic! You are really the Supreme Hookshot!
Kayvan: Is that a compliment? Doesn't really make me happy...
Helbet: Well, the relic at the first spot has been salvaged, and the next... fishing spot is just west of here.
Kayvan: Let's get rolling. The sooner I can go back and catch real fish in peace, the better.
Helbet: No problem. Please follow me!
Kayvan: Traveler, we'll be using Harra Fruit as bait this time. My gut tells me this is the most suitable material.
Kayvan: I know a place where the Harra Fruit is the finest. I'll show you the location.
Kayvan: We'll head off first. Let's meet at the next fishing spot.
Icon Quest Step Step Description

This time, Kayvan's bait requires one Sunsettia and one spike of Wheat. Plus, he demands another one Harra Fruit picked from a particular place...
(Approach the marked area)
Paimon: Another wave of monsters at where Kayvan mentioned, again?
Paimon: Why do the materials he chooses keep getting snatched by monsters...?
Paimon: (TravelerTraveler), we should get the Harra Fruits back!
(After defeating the Fungi)
(Obtain Special Harra Fruit Special Harra Fruit)
Paimon: Done, we got the material!
Icon Quest Step Step Description

Bait materials are all ready. Let's take them to Kayvan, and see what he can catch.
(Talk to Helbet, optional)
Helbet: I'm counting on you two. If you find the material, give it to Mr. Kayvan. Time is pressing!
(Talk to Kayvan)
Kayvan: You are back. Found the special material?
(Submit Sunsettia Sunsettia ×1, Wheat Wheat ×1, and Special Harra Fruit Special Harra Fruit ×1)
Kayvan: Okay. Here goes the fishing again.
Kayvan: I need to concentrate. Please don't make any noise...
Kayvan begins to focus on fishing...
Helbet: Argh! Look over there! So many Slimes!
Kayvan: Huh? I've never seen anything like this before.
Icon Dialogue Talk Leave them to me.
Icon Dialogue Talk You just keep fishing.
Paimon: What's with all the troubles when Mr. Kayvan is fishing...
Paimon: Anyway, let's just get rid of those Slimes first!
(Talk to Helbet, optional)
Helbet: Please help me drive away the Slime! They could ruin our salvage!
(Talk to Kayvan again)
Kayvan: *sigh* Please help us deal with the Slimes...
(Talk to Helbet or Kayvan after defeating the slimes)
Helbet: You guys are so good! Thanks a lot!
Helbet: When all the relics are recovered, I will apply for more compensation as your payment.
Kayvan: You just don't believe I can hook a real fish, do you...?
Kayvan: Wait, something big is on the hook!
Kayvan lifts the rod hard...
Kayvan: What's this...?
Helbet: Ah, this is another pack of the relics! Great!
Helbet: I didn't expect it to go so well. You've recovered two relics now! What a hook, Mr. Kayvan!
Kayvan: I shouldn't have said that...
Icon Dialogue Talk There are tons of fish in the river. Not so for relics.
Kayvan: But I haven't caught a single fish!
Paimon: Look at the bright side. We've recovered the relics. It's a good thing.
Helbet: The last fishing spot is near Vimara Village. A much safer place for fishing. Let's get moving.
Kayvan: Yeah, yeah. Off we go...
Kayvan: This is so weird. Is there something wrong with my bait, or the way I fish...?
Kayvan: Never mind. Traveler, please find some fresh Zaytun Peaches for me this time.
Kayvan: Since it's the last spot, I'll have to use my special bait.
Kayvan: I'm counting that on you, Traveler.
Icon Quest Step Step Description

This time, Kayvan's bait requires one Sunsettia and one spike of Wheat. Plus, he demands another three Zaytun Peaches picked from a particular place...
(Collect Fresh Zaytun Peach ×3)
(Approach the Zaytun Peach northwest of Vimara Village)
Paimon: Whoa! Where did this Whopperflower come from!?
Paimon: If we want that Zaytun Peach, we gotta take them down!
(After obtaining three Fresh Zaytun Peaches)
Paimon: One, two, three... These Zaytun Peaches should do. Let's bring them back to Mr. Kayvan.
Paimon: Hehe, it actually went pretty well this time.
Icon Quest Step Step Description

Bait materials are all ready. Let's take them to Kayvan, and see what he can catch.
(Talk to Helbet, optional)
Helbet: This would be the last of the relics. Please find the materials to help Mr. Kayvan do his job.
(Talk to Kayvan)
Kayvan: That was fast! You found the special material?
(Submit Sunsettia Sunsettia ×1, Wheat Wheat ×1, and Fresh Zaytun Peach Fresh Zaytun Peach ×3)
Kayvan: Looks like everything's going well. Time for one last fishing attempt.
Kayvan: Whew... Third time's a charm. Please let me hook some fish! Even a teeny-tiny one will do.
Kayvan prepares the bait and begins fishing...
A third soaked package is pulled out of the water by the wire after a while.
Kayvan: See it yourself... I don't want to look at it...
Helbet: Alright, let me take a look... Good, there's no damage at all.
Helbet: Perfect, Mr. Kayvan! The power of Supreme Hookshot, again!
Kayvan: Yeah, haha... As long as you have what you wanted...
Paimon: Three packs with three hooks... Yet not even one fish came to bite the hook...
Icon Dialogue Talk That's what makes Mr. Kayvan so impressive.
Icon Dialogue Talk This is certainly one of a kind I guess...
Kayvan: Hey! I've been serious about catching a big fish, not antiques!
Kayvan: Call me bad at fishing or whatever...
Kayvan: But it's been so many times! Even one with the worst luck should have gotten some fish!
Kayvan: But none's ever come to me!
Paimon: Hmm... This is strange indeed...
Helbet: Well, Mr. Kayvan, if you are interested, I can introduce you to a researcher who specialized in fishing.
Helbet: He's worked on the design of many popular fishing rods and baits.
Helbet: I don't know exactly why you couldn't hook a fish. But... It doesn't hurt to ask a professional.
Helbet: Maybe he'll be interested in you.
Kayvan: You mean interested in the fact that I lift my hook with everything but fish?
Kayvan: But you are right. This is my chance to see what's wrong with my skill.
Helbet: Sure. Leave the rest to me!
Kayvan: But do some bookworm researchers really know fishing?
Kayvan: Oh... I almost forgot! Thank you for the help, Traveler. This is your payment. Please take it.
