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

Mechanics[edit]

Damage Block has a chance to proc from attack damage, but not physical damage from abilities (except for Moon Glaives icon.png Moon Glaives, The Swarm icon.png The Swarm, and physical damage reflected by Blade Mail icon.png Blade Mail or Dispersion icon.png Dispersion). Only the attack damage from wards (Death Ward icon.png Death Ward, Mass Serpent Ward icon.png Mass Serpent Ward, Plague Ward icon.png Plague Ward) is not reduced by Damage Block. Unlike 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[edit]

Main Article: Item passive 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, will any others roll. In other words, when two sources of Damage Block proc on the same attack, 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.

Example:
When having two Stout Shield icon.png Stout Shields, the chance of blocking damage becomes:

1 - (0.5 × 0.5) = 75%

When having one Stout Shield icon.png Stout Shield and one Vanguard icon.png Vanguard, the chance of blocking damage becomes:

50% chance for Vanguard to proc, and 50% × 50% = 25% chance for Stout Shield to proc

This is because half of the time Stout Shield procs at the same time as Vanguard does, but since Vanguard has the higher block values, Vanguard gets prioritized, effectively negating half of the Stout Shield procs.
