Using this site
UO Toolkit · last changed with v35.213.2
It is free
The whole tool is free and stays free. Nothing is held back, there is no paid tier, and there never will be. There is a donation link in the About section for anybody who wants to put something towards the hosting; it buys nothing and is never asked for anywhere else.
If you are going to spend money on Ultima Online, spend it with Broadsword. This tool exists because of their game.
What this is not
This is an unofficial, player-made tool. It is not affiliated with, endorsed by or sponsored by Electronic Arts or Broadsword Online Games. Ultima and Ultima Online are trademarks of Electronic Arts Inc., and the game's art and data belong to them.
Everything here describes the official shards only. Free shards and emulators run different numbers, and a figure from one of them would be wrong here.
The marketplace is gold only
Advertisements on this site are for in-game gold. Nothing is bought or paid for here — the site carries the ad and the players meet in game. Offering or asking for real money is not allowed, is filtered, and will get a listing removed.
Behaving
Do not post slurs, sexual content, or anything you would not say to somebody's face. Ordinary swearing is fine and is covered over rather than refused. Reports go to a human. Ratings and comments cannot be edited or deleted by the person who wrote them — that is what makes them worth reading — but they can be reported and removed.
The numbers
Every figure here is taken from uo.com or the game itself, and anything uo.com does not publish is marked [!] as unpublished on the screen it appears on. The tool tries hard to be right and is not a substitute for testing something yourself.
Copyright
The tool, its code, its data and its design are © 2026 the author of UO Toolkit, all rights reserved. You are welcome to use the site. You are not licensed to republish it, sell it, rebrand it, or reuse its parts elsewhere.
