I've updated the Complete EDB Guide:

MTM can be simplified, according to initial tests, and I have also added a way that buildings can be made indestructible. I think this may well be a new finding (?) - I'm afraid I've been so caught up in the depths of the tech trees for the Fourth Age mod that I may have lost touch with old posts.

I really must update things more often.

Your feedback and testing is always appreciated.
