How does Deflection work?

[NorthernSquirrel]

I've been planning to create a Death Godlike Cipher who uses Greatsword/Arquebus and all ins on Might/Resolve. One of the things I was thinking about was that since the initial defenses for the cipher class are quite low except for deflection, I could make the character "tanky" through using deflection and blind debuffs. By combining Psychovampiric shield with a very high resolve and blind debuffs, I could then make him survive melee combat through people not being able to hit him well enough since the gap between enemy accuracy and my deflection is so high.

 

To people who have played the beta, or are in the know of the systems, has anybody tried this? How does deflection actually work? Can I find the math behind it (or other game mechanics) somewhere?
