Building a barb

[Munkay]

The what quest?  Is it in act 5, 4, or 3?  If you're talking about the rescue the barbarians, it's Qual-kek, or something pronounced like that, and the shield's block doesn't change.  Mephisto is also in the Que-Hagan of the zakarum religion, but he doesn't always give you a shield, so that's probably not it.

I beleive he is indeed talking about the "Qual-Kek" quest in act 5. Or alternatively known as the 'Save the Barbarian' quest.

Between his name, the act 3 area and its subsiquent unique armor (Que-Hagen Wisdom is it?) its a easy mistake to make.

As far as the block rate, you are correct that a shields block doesn't change, but I beleive Unreal was refering to boosting the stat dex to increase the character's chance to block with whatever shield that is used.
