The Bat Hook is a rare pre-Hardmode grappling hook which is received by opening Goodie Bags (0.67% chance). It launches a single hook which reaches 31.25 tiles at maximum length.
On Old-gen console, , and tModLoader, the Bat Hook has a pull-in speed of 16 and a hook velocity of 15.5. This is the fastest pull-in speed of any hook in the game.
On the Desktop version, Console version, Mobile version, and Nintendo Switch version, the Bat Hook has a pull-in speed of 13 and a hook velocity of 13.5, which still makes it a very fast hook that can be acquired in the early game. It has the longest reach of all pre-Hardmode hooks, as well; still, some players may find a multi-hook (such as the Ivy Whip) preferable.
- The Bat Hook is most likely a reference to DC Comics' fictional superhero Batman, who uses a grappling hook which reels in very quickly, usually launching him up onto ledges.
