I figured out I should go and edit this script to add the targeting and fix the healing so it's ready to run since so many are asking for it.
Enjoy!
If there's any other problem besides you getting stuck because you get druck and walk up the stairs, ask.
Do not forget to first run the XBST FILE and then LOAD the LUA.
THE SCRIPT IS NOT DONE BY ME
IT IS DONE BY @Hypn0ticKi11er
I have just made some changes to in for the healing setup and the targeting.
