Hello,

I heard som rumors that it is harder to destroy a citadel in Null, if the ADM of the system is high. I did not find any document that confirms that. All documents that I found about the ADM just refer to the entosis link.  
Does anybody know for sure whether citadels, engineering complex, … are affected in any way by the ADM? Does somebody have a link with “official” information?

Regards,
