Toys no longer in bags? Yay, more space!
New weird fishing system? Yay, less space!
The inventory situation improves with your skill and fishing gear. Once you cap out at 700 you stop getting so many small and regular sized fish and once you get an ephemeral rod and worm supremes you are catching nothing but enormous. Fish in pairs and throw the pheromone fish at each other and you can get over a thousand effective skill
You do end up vendoring a lot of fishing rods and strange baubles.
What's the new weird fishing system?
I need to be fed all this new info!
75% of your catch will be trash fish until you fish up a catch-specific 'bait' item that flips the odds to 75% of the targeted fish.
There is a new lure, worm supreme that gives +200 fishing skill for 10 minutes and is pretty commonly fished up if you go at it long enough.
You can now fish up Ephemeral rods, +100 fishing skill with a 24 hour duration.
You can now fish up pheromone fish, must be used on a friendly target, grants +100 skill and stacks with everything else.
There are now 'sizes' of fish. Small/Normal/Enormous that produce more flesh per catch. Small fish require a stack of 20 to convert into usable flesh. Normals require a stack of 10, Enormous a stack of 5. Your effective skill is what determines the ratio of small/normal/enormous. At ~950 skill 100% of your fish catches should be Enormous.
That's about it I think. I might have left out stuff from the Garrison building, which gives fishing dailies and can be fished at.
