>How would I do a build around blocking?
Endurance is your best friend, you'll want a shield with 65-70% guard boost or more and 100% physical negation or whatever element is relevant to a boss fight.
Talisman wise there's only two specific choices:
>Two Headed Turtle Talisman
You'll want this for Stamina regen
>Curved Sword Talisman
Vital for boosting your guard counter damage
The Greatshield Talisman is not really worth it unless you want to play Fashion souls and salvage the less useful shields with it, same with the Pearl Shied Talisman, shield grease is free and helps more than either of these will ever do.
If you're looking for weapons that have good 1H guard counters you'll want to consider most piercing weapons, spears in particular have an excellent guard counter and so does the Sword Spear since despite being a great thrusting sword it uses the Spear's guard counter, straight swords are not bad either, maces, axes and surprisingly martial arts have all good guard counters.
If you want to use spells, Scholar's Shield is shield grease on crack, extremely good on the Carian Thrusting Shield especially if you really want to focus on guarding since that bonus does apply to the guard points of a Thrusting shield's unique ash of war or two handed attacks.
If you want to work around weapon blocking and not use a shield then things get more interesting as there's weapons that are specifically built for weapon blocking like the Curseblade Cirque which can deal immense guard counter damage but you'll really want to rely on the Deflecting Hard Tear in that case.
