The weapon's long description reads as follows: "A whip made from a thorny vine. Get cracking!"
Like all whips, it will quickly strike the point where the cursor crosshairs are when fired. The Vine Whip has a maximum length of 10 segments (and a minimum length of 4 segments) while being cracked; each segment is 0.375 tiles long, allowing the whip to extend up to 3.75 tiles out from its handle. If one attempts to strike something out of range, the whip will extend as far as it can in the aimed direction.
The Vine Whip can be cracked once every second. The striking end of the whip has a base power of 11.25, and each segment of the whip has a base power of 3.75. If both the striking end and one segment hit the same target, this produces a base hit power of 15. An enemy hit by multiple segments will only take damage from one segment.
When upgraded at a Weapon Upgrade Anvil to tier 6, striking end base power and segment base power increase to 15.75 and 5.25, respectively, producing a base hit power of 21. Additionally, the Vine Whip's appearance changes to the one shown below.
Apart from the addition of a gold star to the name, no other changes occur as a result of the upgrade.
