Web Slinger

The Web Slinger is a variation of the Grappling Hook. It is acquired in Webbed biomes in a Web Covered Chest which is exclusive to the biome. What makes this different from Grappling Hook is that it can have 8 grapples shot out at once. This makes this useful for precise movement. Despite being able to shoot 8 grapples out at once, it is relatively slow and has extremely short range which one might consider it to be obsolete.

Tips

 * You can press the grapple hotkey (E by default) to grapple faster and easier, without even having the Web Slinger equipped on the action bar.
 * You can use the Web Slinger to negate falling damage by grappling the ground just before you hit. This is easiest done in singleplayer mode with autopause switched on.
 * You can use the Web Slinger to crawl around caves for mining in harder to reach places, or to carefully mine around dangerous obstacles like Meteorite or Spikes.
 * You can shoot it multiple times without needing to wait for the first one to latch onto a surface.

Trivia

 * The quantity of grapples that this item can have out at one time may refer to the the fact that spiders have eight legs.
 * The name Web Slinger is most likely a direct reference to spider-man.
