Damage block
Damage Block is a mechanic that reduces physical attack damage a unit takes by a flat amount. Most damage block abilities are chance-based and passive.

Mechanics[edit]
Damage block reduces any physical damage a unit takes from attacks or from cleave, with the exception of damage dealt by the attacks of ward-type units. Damage block does not trigger against physical spell damage, with the exception of the spells listed below. Unlike armor, damage block reduces a fixed amount of damage, instead of a percentage.
When damage block triggers, it blocks damage before other damage reducing effects do. This means that the higher the unit's armor is, the less effective damage block gets. See final attack damage for the complete calculation.
All chance-based sources of damage block use pseudo-random distribution.
Innate Damage Block[edit]
Passive
Self
Notes:
- All melee heroes have this innate damage block ability by default.
- Does not work against wards ( Plague Ward, Mass Serpent Ward, Death Ward).
- Does not reduce physical damage from spells, except from Moon Glaives and The Swarm.
- Stacks with all other sources of Damage Block.
- Damage Block uses pseudo-random distribution.
Blocked Spell Damage[edit]
The following abilities' damage is blocked by Damage Block.
1Only returned/reflected physical damage is blocked. Magical and pure damage is not blocked.
Visual Feedback[edit]
When a damage block occurs, a ocher-colored negative number pops up on the unit, with a shield icon on the right side of the -x
number. This number shows the exact amount of damage blocked.
Stacking[edit]
The proc chances of all sources of Damage Block work independently from each other.
- When having a single source of Damage Block from multiples of the same item, the chance for Damage Block stacks multiplicatively.
- When having multiple sources of Damage Block, the one with higher proc chance or Damage Block values gets prioritized, while the other sources do nothing.
This results in a diminishing stacking behavior, and it can be defined as
With b
being the Proc Chance of Damage Block.
Examples[edit]
- Example 1
- When having two Vanguards, what is the chance for Damage Block to proc?
- Therefore, when having two Vanguards, the chance for Damage Block to proc becomes 64%.
- Example 2
- Warlock is affected by Guard and he has one Vanguard in his inventory. What are the chances for both sources of Damage Block that Warlock currently have to proc?
- Since Vanguard has a lower proc chance, therefore Vanguard's Damage Block proc chance is multiplied with the higher proc chance of Guard, resulting in 60%. So now, there is 100% for Guard's Damage Block to proc, and a 60% proc chance for Vanguard.
- This means that half of the time Vanguard's Damage Block will proc at the same time as Guard does, but since Guard has the higher block values, it gets prioritized, effectively negating half of the Vanguard's procs.
