Nimbus

The Nimbus is a Mount summoning item that can be bought from the Tracker after completing the "Off Cloud Nine" contract. When used, it summons a ridable Wyvern.

The Wyvern can fly quickly in any direction and hover.

After 7.5 seconds of being constantly in the air, it will begin to descend automatically, and must land on the ground again to reset its flight time. It has a top speed of 42 miles per hour and negates fall damage.

Trivia

 * The description of the mount is a reference to the Youtuber HappyDays, as they appear in his videos a lot more than in the average playthrough.
