9th Dawn III

This achievement is straight-forward enough that it doesn't need a guide, but there are some tips I can offer:

- Wait to do this until you've got the legendary pole/the Sticky-Magic Fish Bait. It will help.
- Getting your fishing skill to 100 helps (albeit only a little)
- Don't cast your pole with max power. I figured this out annoyingly late. It doesn't help you catch rare fish, it doesn't help you catch bigger fish. All it does is make it increase the distance you have to reel the fish in. Just bump the stick and cast as low-power as you can. Oftentimes, you'll be able to immediately reel in and catch the fish.


Note: All fish except one can be found in the overworld. The final fish, King Carp, can only be found in Olsyn Cove.

Olsyn Cove can be found near the ice area:


And here is where I caught the King Carp fish inside:


I found that moving and fishing around different spots of the peninsula helped, but it could have just been dumb luck.
