I thought I read somewhere that the number of mechadendrites a Tech Priest can have is limited by his Toughness Bonus. Am I delusional or did I get that from another system? I cannot find anything even remotely close anywhere in a Dark Heresy book. Can someone help me out here?

It's in the errata, pg. 9 under Implant Systems

Well that would be why I could not find it in a book! It's in my binder… Dur….

Thanks!
