The weapon's long description reads as follows: "A rope fashioned into a whip. Get cracking!"
Like all whips, it will quickly strike the point where the cursor crosshairs are when fired. The Rope Whip has a maximum length of 14 segments (and a minimum length of 3 segments) while being cracked; each segment is 0.375 tiles long, allowing the whip to extend up to 5.25 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 whip can be cracked once every 1.2 seconds, and the striking end of the whip has a base DPS of 9.0, producing a base strike power of 10.8.
When upgraded at a Weapon Upgrade Anvil to tier 6, the striking end's base DPS increases to 21, producing a new base strike power of 25.2. Additionally, the Rope 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.
