i'm working on a desert island for my world, and for coconuts in my trees i was going to use conduits but they look a bit mid so my question is whats the best way to get lots of heavy cores. Preferably without trading with villagers for maps beacuse i have gone through over a hundred cartographers and they just give me the same maps for already looted ones. I already have an ominous key farm.
