Ivy Whip

Information
The Ivy whip is an upgraded form of the standard Grappling Hook, boasting a longer reach and three seperate vines or chains. These three vines can be used for ascent, descent or positioning. This allows a player to position themselves in the middle of a space, unlike a traditional grappling hook which attaches you straight to the target surface. This allows for a significant improvement in the ease with which walls can be placed.

The hooks of an Ivy whip will detach after about a minute, however, so it's important to re-place your hooks every so often when engaging in longer projects.

The Ivy Whip does not damage Monsters, but it does break grass, vines and pots.

Trivia

 * In the alpha version of Terraria the Ivy Whip did damage to enemies, just like the grappling hook.
