Hook of Dissonance

Fire it, and the moment the hook grabs you are already there. There is no rope to ride and nothing can touch you in between, so it will pull you clean through a crowd that has you cornered. Falling sand and silt cannot hurt you during the move either, which makes it the safest way to travel through a collapsing desert. If you aim at a gap you do not fit through, the game places you at the nearest spot that does fit instead of failing.

You arrive with no momentum whatsoever. Whatever running speed or fall speed you had built up is gone. That makes it poor for chaining movement across open ground, and excellent for repositioning in a fight where the point is to be somewhere else immediately. It also retracts far faster than any normal hook, so a missed shot costs you almost nothing.

Stacked platform arenas are its home. You can climb the whole tower in a second and skip past everything flying between the rows, which is how you get out of trouble during invasions and boss phases that flood the air. It covers a lot of what the Rod of Discord does if you have not been lucky enough to find one, and it lets you keep moving without dropping Shroomite stealth.
