Hooks

Grapling hooks are long reach tools which when launched fly some distance until they are far away from you. If they hit a block, they will hook to to it and pull you.

There are eleven (as of patch 1.2) hooks currently in game:
 * Grappling Hook - The original grappling hook made from 1 Hook and 3 Iron Chains or bought from the Goblin Tinkerer for 2 Gold Coins.
 * Skeletron Hand - Dropped by Skeletron
 * Dual Hook - The Hardmode upgrade of a Grappling Hook. It is only dropped by Mimics.
 * Ivy Whip - The Jungle upgrade of a Grappling Hook. It is craftable pre-hardmode with 12 Jungle Spores, 3 Vines, and one Grappling Hook at an Iron Anvil.
 * Web Slinger - Dropped by spiders (patch 1.2)
 * Sapphire Hook, Diamond Hook, Ruby Hook, Topaz Hook, Amethyst Hook and Emerald Hook - Crafted (patch 1.2)
