This is a text-based re-enactment of Boromir's death scene from The Fellowship of the Ring.
The simulation uses Dungeons and Dragons 3rd Edition rules.
Originally implemented in Python in 2003. In 2011 it was ported it to HTML5 by toolness.
The HTML5 version uses the Application Cache to enable offline use, and has been tested on IE8, Opera, Chrome, Safari, Firefox, and iOS.
