Help me out with Adamic (language of Adam)

So correct me if I'm wrong here, in understanding the system regarding having Adamic 5 (a very difficult feat), I am led to believe that you pretty much brush most Magic Resistance aside?

This is of course due to the automatic creation of a lasting permanent arcane connections and a penetration multiplier of +5. These are practically useable with any voice range spells or rituals then, correct?
