Force Staff:

Force Staff is a Dota 2 item that lets its user push a unit, including themselves or another target, a short distance in the direction they are facing. It is commonly used to help allies escape danger, reposition during fights, or move enemies and teammates across terrain and obstacles.

Because it changes positioning rather than dealing damage, Force Staff is valued for mobility, saves, and chase control. It is a standard utility purchase on supports and other heroes that need a reliable escape or playmaking tool.
