Razor is an Assistant program (similar to the popular UOAssist) for player-run Ultima Online (freeshards) developed by the RunUO team. Razor not only allows you to connect to freeshards, but has many features to make tedious tasks in game quite a deal easier. It would take quite a while to list all of its features here.
Custom Freeshard Patches
Many freeshards have available or even require custom patches which extend the gameplay. Razor does not include a way to download or incorporate these patches when connecting to these freeshards. You can download the patched separately and incorporate them manually yourself, but this is a permanent solution and is not reccomended. Therefore, it is recommended that you use Razor in conjunction with a different tool to connect to your freeshards of choice.
