Fish: Hyphalosaurus
Location: Labyrinthos
Hole: Deepmoat
Bait: Mayfly (Mooch, Intuition)
Conditions: 09 – 12
Folklore Book: Ilsabard and the Northern Empty
Min Gathering: 3300

📋Window Prep
Before going to Deepmoat, get 9-10 Angler’s Art stacks at another Labyrinthos fishing hole. This is mostly to make prep easy and clean so we don’t accidentally pre-pop intuition in Deepmoat. If you know how to avoid it, though, you can fish in Deepmoat.

Once you’ve done that, head over to Deepmoat and cast out with Mayfly. Catch TWO Astacus Aetherius, using Identical Cast after catching the second. Finish off by using Prize Catch, then wait for ~08:52 before casting out again.

🎣Catching Hyphalosaurus
Once 08:52 rolls around, cast out to get your third Astacus Aetherius. This will give you the Fisherman’s Intuition buff for Hyphalosaurus. Mooch the Astacus Aetherius you just reeled in at or after 9:01. When you mooch a handful of things could happen. Regardless of what happens, you should NEVER reel in early!

First, you could get a !! bite before 16s. If you get a !! bite before 16s, reel it in. If it’s not Astacus Aetherius, you need to get another one to mooch.

Second, you could get a Astacus Aetherius on that pre-16s !! bite, use Makeshift Bait, then mooch it. Astacus CAN mooch into itself (making a loop) but it’s easily broken by Labyrinthos Tilapia and Xenocypris.

Third, you could get a non !!! bite after 16s. Do NOT attempt to reel it in to save time. Get another Astacus Aetherius to mooch.

Fourth, you get a !!! bite on the mooch, this is Hyphalosaurus. Use Hook to reel it in, or Powerful Hookset if you are using Patience.

🏗 Rebuilding Intuition
It’s possible to easily rebuild intuition after the first one falls off. Reel in any !! bites after 13s. If it’s Astacus Aetherius, use Identical Cast, cast out, then use Double Hook. If it’s a !! bite after 16s, you can safely Triple Hook for 3x Astacus Aetherius.

Good luck and happy fishing!
