This prevents damage and other modifiers being applied, although it does not prevent missile piercing due to Pierce and Piercing Attack. The following can be blocked: Melee attacks Arrows fired by bows Bolts fired by crossbows Javelins Throwing axes Throwing knives Missiles applying physical damage The following cannot be blocked: Level >49 Fire Arrow Level >49 Cold Arrow Lightning Bolt Molten Boulder explosion Tornado periodic radial damage Armageddon radial impact damage Paladin Smite Charging Claw Vipers and Reanimated Horde Classic Chance to Block = min(Shield+Bonus , 75) % Expansion Chance to Block = min( (Shield+Bonus) * (Dexterity-15) / (clvl*2) , 75) % 0 Shield Base Chance to Block of shield, auric shield or shrunken head Bonus Increased Chance of Blocking from items and Holy Shield Dexterity Dexterity (including bonuses) clvl Character level Kalkulatoren: Blockrate (D2Wissen.de) Ceiling of 75% Chance to Block applies when stationary (whether idle, attacking or casting), walking or using Whirlwind. Chance to Block is reduced to 1/3 while running, after this ceiling is applied (so maximum 25% Chance to Block while running). [1] Chance to Block displayed on the shield itself is the sum of its base value, a class-specific bonus and Increased Chance of Blocking on the shield itself (including Holy Shield when active). Although 75% ceiling is applied to its displayed Chance to Block, any excess and Increased Chance of Blocking from other items is still taken into account when calculating actual Chance to Block displayed when cursor is over Defense field in character screen. Dexterity required for maximum 75% Chance to Block is calculated as follows: Dexmin = 15 + {150*clvl / (Shield + Bonus) } Base Chance to Block Every shield, auric shield and shrunken head has a base Chance to Block, to which a class-specific bonus is added.
