It worked for a while, I remember when I got it I tested it and it was all cool.

 

Now it doesn't work at all. I don't get the +6 deflection bonus for equipping a shield neither the +20ish Reflex bonus associated with the talent. It's just as good as if it wasn't there at all.

 

Tested it several times, shut the game down and reloaded it, dismissed Eder and readmitted him to the party, nothing will work.

 

Just to toss the numbers there.

 

Unequipped stats: 

 

Deflection 75, Reflex 60

 

 

Expected stats after equipping Exceptional Large Shield with Weapon and Shield talent:

 

Deflection 101, Reflex 86

 

 

Actual stats after equipping Exceptional Large Shield with Weapon and Shield Style talent:

 

Deflection 95, Reflex 60

There is bug in equipping stuff with double clicking them that causes passive talents not work, which is probably that has happened in your case.

 

They have promised to fix it in next patch, which should be out this week.

Alright thanks
