This is the yoyo to learn the class on. You hold the button, it parks itself on whatever you aimed at and grinds away while you keep running, which is exactly what you want against early bosses where staying alive matters more than raw output. The long spin means you are not constantly re-throwing it mid dodge.

Getting it means a real trip through the Underground Jungle for stingers and spores, which is a serious errand at that point in a run. You come back with one of the strongest options available before Hardmode.

Add a string and a counterweight as soon as you can afford the slots. Extra reach changes how safely you can hold a target from across a room, and that matters more to your survival than a small damage upgrade would. A Yoyo Bag later folds all of it into one slot.
