isn't it possible to make a virtual mouse to do the clicking?Shouldn't be too tough.
Simplest would be a C# (preferred due to its close connection to Windows) or Visual Basic proggie that attaches to the Windowed (important) Rohan client area and watches the color at near the left side of your health bar. Of course you won't be able to auto rez yourself without running afoul with GameGuard, but you can make a loud racket (alarm) if you die or are very close to dying.
This isn't something that is hard to cobble together with the help of Visual Studio and a little time & effort.
