Fledgling Wings

That is the whole appeal. They fly, they cancel fall damage, and they do both at a speed that will feel slow the instant you own anything else. There is also no horizontal push at all, which no other pair does, so you build sideways speed exactly as slowly as you would on foot.

The odds out of Skyware Chests and the sky crates are low enough that farming for them costs more time than the mobility repays. Spectre Boots with a jump accessory covers most of the same movement much sooner, and the Lucky Horseshoe sitting in the same chests handles the fall damage half by itself.

A Journey character starts with a pair, and in that mode they can roll a modifier the way any other starting item can. The ones from chests never do, with the exception of the seed where everything in a Skyware Chest arrives already at the top of its modifier list.

Paired with an accessory that boosts flight speed they punch well above their tier, reaching numbers you would not normally see until Hardmode wings. That combination is the one reason to go out of your way for a set.
