White Horseshoe Balloon

Fall damage stops existing, your first jump clears well over a story, and a second jump lands on top of it with a burst of speed. That speed kick is worth learning on purpose: firing the second jump mid air is one of the fastest ways to reverse direction without shedding all your momentum. Letting go of the jump key partway through cuts the second jump short if you need to slip under something.

Wearing several horseshoe balloons at once only pays out the height bonus and fall protection once. The extra jumps are the only part that adds up. Also, the recipe wants the plain Lucky Horseshoe; the Obsidian Horseshoe is not accepted, so save the obsidian version for a different combine.

Jump height drops when you are submerged rather than rising the way swimming normally feels. If you are planning a route through a flooded shaft, do not assume the same gaps clear.
