Final Fantasy 15 – Why Was the Regalia Type-D Reverted in Chapter 7?

From my experience with fishing in FFXV the way you entice the fish is by doing short bursts of reeling in while moving the lure from left to right to get it moving. Once the fish bites make sure you get the QTE to hook the fish so you can start the reeling in process.

After you enter the reeling in phase slowly start to reel in the fish if you start to see the red and white flashing bar stop reeling in order to keep your line from snapping. If the bar tells you to move your left stick to the left or right make sure you do as such since it builds tension a lot if you fail to move your line. Also be sure to pay attention if the fish decides to jump in the water since it will prompt you for another QTE to keep the fish on the line. Repeat until you catch that fish!

And make sure you feed that cat!

I have not found any means to obtain bulk lots of ore, so far in my gameplay (Chapter 6 30h+).

The best way to gather ores is to speak to a local restaurant proprietor, who will mark the local procurement points on your map. The pickaxe icons are the ones to keep an eye out for.

Then you'll need to visit these spots and collect the ore. The procurement spots do seem to regenerate after a time. So you can 'farm' these ore nodes by revisiting them once they've regenerated. The icon will change from grey back to yellow.

Unfortunately I haven't been paying enough attention to notice if certain ores spawn in the same spot each time, so that you can gather multiples of the same. I know the treasure spots do contain the same items every time though, so the ores may well do as well.
