Make sure it works with the chlorophyte extractinator as well of course. I like the idea of making it work with the staff of regrowth in an area around you if it doesn't do that already. I've seen folks asking if it can place blocks or auto fish. Neither is a particularly good idea IMO. You can't move while using it, and fully afk fishing isn't really balanced by game standards.
I've suggested dirt scarab bombs to help block grinding and platform/biome making rather than a stress ball use. Someone suggested a compressed platform that springs out placing platforms horizontally like how rope coils work vertically. The digging molecart seems like a valid existing method for automatically spanning distance in skyblock, though it's a bit of an investment. Honestly, I haven't used it before. The iron is too precious at the time that I want to build to the ocean.
