I would like to suggest making driftwood a beach spawn, like the seashell, after ending up with a pile of 5-10 driftwood at my feet every time I want a fish.
It seems you can’t fish up a new item when you have something in your hand. With the other items you fish up, you can holster them, allowing a new item to be fished up. However, driftwood can’t be holstered, so you have to drop it on the ground to try for a new item. Getting a fish for sedative poison is a bit aggravating when compared to the ease of picking an emetic mushroom.
The fishing for items is a fun idea, but at the end of the day I’m here to play Hitman, not create driftwood piles.
