The point is inventory space. Every information accessory you have been hauling around folds into a single item, and that item also takes you home. Unlike the parts that went into it, this is not an accessory, so it does nothing in an equipment slot and everything from your bag.

Expect the Angler to be the bottleneck, since several of the fishing accessories only ever come from quests, and he decides when you get them. The whole thing is finishable before hardmode, which makes it one of the strongest quality of life goals in an early run.

The recall is slow. It has one of the longest use animations in the game, and standing still that long is exactly what kills you when you are trying to escape. If something is chasing you, start the animation early, or keep a Recall Potion for emergencies and save this for convenience.
