Two-Weapon Fighting

[Joe the Rat]

And partially unrelated, are bucklers still strapped to the arm like in previous versions, or are they like historical bucklers and grasped in the fist?

The playtest material is rather vague on shields altogether, but if I were to hazard a guess, it's buckled on to keep your hand free. That doesn't mean you can't decide your game has held bucklers.

What I want to know is if they decide to class buckler as a light weapon for shield masters, for when you absolutely, positively have to punch someone in the face while stabbing them.
