The Bottom Line: Bioscanner — How to Get & Use is one of those crafts that looks simple on paper but becomes a bottleneck if you don’t plan ahead. I’ve been in the situation where I needed one more and had to swim back across three biomes to get it. Build extras. Store them in a locker. Future you — the one who’s 200 meters deep with a Leviathan on your tail — will be very grateful.
