Whipvine tube

Whipvine tubes are magic items manufactured in the Deluvian Empire. They're primarily used for battlefield mobility, but can also be used offensively to pull an enemy toward the user.
Deluvian Leader made use of a whipvine tube in battle against the party and B'ob's forces in Episode 2. Draven retrieved an unused specimen after the battle with the intent of reverse-engineering it, but this was determined not to be cost-efficient.
