The new Flawless White armour has a Shield Bonus: Shield +6, which can be upgraded to Shield +8 at tier 2.
Dragoncraft Armor has Shield +4 and Restored Dragoncraft Armor has Shield +6.
Epic Daggertooth's Belt ML:23 has Armor Mastery +3 and ML:24+ has Armor Mastery +4. These provide an enhancement bonus to armored MDB. Note, this is different wording to the old Daggertooth Belt. Not sure if this still does not stack with Fighter Armor Mastery.
