Info
Damage Block is a passive ability that gives the wielding unit a chance to block some physical damage from an attack.
Mechanics

Damage Block has a chance to proc from attack damage, but not physical damage from abilities (except for Moon Glaive, The Swarm, and physical damage reflected by Blade Mail Item Old Abilities Changelogs Blade MailBL A razor-sharp coat of mail, it is the choice of selfless martyrs in combat. Cost2200 Bought FromArmor Active Damage Return Bonus +10 Intelligence+6 Armor+22 or Dispersion). Only the attack damage from wards ( Death Ward, Mass Serpent Ward, Plague Ward) is not reduced by Damage Block. Unlike armor Armor is an attribute shared by all units. Armor is used to determine the amount of damage reduction (or amplification if an armor value is negative) a unit takes from physical damage sources. Higher armor
, Damage Block only reduces a set amount of damage, making it less useful over time.
Damage Block occurs as first step of incoming damage manipulation. See Final Attack Damage for the complete calculation.
All items that use Damage Block mechanics use pseudo-random distribution.
Most Damage Block items block different amounts depending on whether the user is melee or ranged.

Stacking
Only one instance of Damage Block can proc at a time. When multiple sources of Damage Block are present, the source with the highest blocked damage is checked first, and only if it does not proc any others roll. In other words, when two sources of Damage Block have the same chance to proc, the one that blocks more damage takes priority. While the amount of damage blocked from multiple Damage Block sources does not stack, the proc chance stacks multiplicatively. For instance, when having two Stout Shield Item Changelogs Stout ShieldBL One man s wine barrel bottom is another man s shield. Cost200 Bought FromArmaments Passive Damage Block Disassemble?
