Magic Water Dropper

A dropper is pure decoration. Place one and that spot drips forever on a loose timer, with no gameplay effect at all. The same drips appear naturally when a world is generated, wherever a pocket of liquid sits above a ceiling and looks like it is leaking through, so the crafted item is a way to fake that look anywhere you want it.

It only goes on the underside of a block, and the item is consumed the moment it goes down. Removing one means mining the drip with a pickaxe, and nothing comes back, so decide before you commit. Swapping out the block above a drip leaves the drip alone. Every one you place also shows on the minimap, which helps you find decoration you forgot about.

Lava is the only version that gives off light, which makes it the pick for a cave room or forge that wants a glow with no visible torch, and its drips cannot burn you. Water and honey are quieter and suit cellars and hive rooms. The shimmer version skips the workbench entirely: throw an Empty Dropper into a pool of Shimmer and it comes back transformed.
