Ring of Swiftness

Are you tired of moving at a xenogrub's pace? Do you have somewhere to be in a hurry? Are you playing Survival mode and just want to get back to your bed without walking for half an hour? Have you dreamt of running at the speed of the wind, leaping from tall cliffs and skyscrapers like a superhero and landing at high speed without a scratch? Or perhaps you'd like an infinitely reusable 10-second speed boost you can add to Favorites? Then this is the mod for you.

On the shelf of a small lamp stand in your room at the Lodge, you'll find a mysterious box that contains a most impressive piece of jewelry - The Ring of Swiftness! Next to that you will find a bottle of Swiftness Supplement, which is infinitely reusable, can be favorited, and has the same effects as the Ring of Swiftness, for 10 seconds each use.

The Ring of Swiftness grants its wearer an immense increase in movement speed, and a total immunity to fall damage. Dash and leap to your heart's content.

Notes:

The Ring of Swiftness takes up no armor slot, so you can wear anything you want at the same time.
The Swiftness Supplement can stack with the Ring of Swiftness, and you can also use the Supplement repeatedly for further stacking speed.
Running at very high speed for a long time may result in temporary texture anomalies, such as grass rendering too slowly; this is simply the console trying to keep up with your new speed. If necessary, take a break, or if you prefer, just keep pushing on and ignore it.
On rough terrain, you may feel that your new movement speed is a bit bumpy; however, if you try it out on a piece of flat terrain such as a stretch of pavement, you'll see that it's smooth, and the intermittent bumpiness is indeed caused by the terrain.
In 3rd person view you'll notice that your character is passing through the full range of running animation motion, which might remind you of a fast-forwarded video of someone running; 3rd person also reduces the swiftness effect somewhat. There's currently nothing I can do about either of these (fairly minor) issues.

Enjoy!
