Frog Flipper

Two accessories folded into one slot, and the swimming half is why most players never bother. Water stops being a problem the moment you own wings or even a decent double jump, so paying a slot for it only makes sense on a dedicated ocean or dungeon trip. The frog half is the useful part: auto-jump plus a softer landing changes how caves feel to move through far more than the numbers hint.

Anything built out of a Frog Leg now adds its jump bonus on top of the others, so wearing this next to another frog tinker is not wasted space. That mostly matters if you want to bunny hop everywhere on foot before flight, which is a perfectly reasonable way to play the early game.
