Evasion is a passive ability that gives the unit a chance to dodge an incoming physical attack. When evaded, the attack gets completely nullified, acting as if it was disjointed Shadow Fiend using a Blink Dagger to dodge Phantom Assassin s Stifling Dagger Disjointing is the act of dodging projectiles, or rather, to cause a projectile to fully lose track of its target. A disjoint is . This means if the attack had an attack modifier Attack modifiers are modifiers which apply an effect to a unit s basic attacks. These effects can widely vary, from healing, to damaging or even disabling effects. Most of these modifiers have their own rules. For , the modifiers are not applied either (with a very few exceptions).

A similar mechanic to evasion is blind. While evasion makes a unit evade incoming attacks from other units, blind makes a unit miss upon attacking other units. Just like evasion, when an attack misses to blindness, it acts as if it got disjointed.

Mechanics

"Miss" appearing upon missing an attack,
"Evade" appearing upon getting missed.

Evasion and blind proc or have a chance to proc upon finishing the attack, which is on projectile impact for ranged units. If it procs, the attack does not affect the evading unit, so that no on-attack effects are triggered. Upon missing an attack on an enemy, a red floating text appears, reading "miss", visible to the attacking player only. The enemy, who was just missed by an attack, also sees a floating text, but in white and reading "evade" instead. Furthermore, a missed attack does not play any of the attack impact sounds.

Stacking

Multiple sources of evasion stack multiplicatively, as well as other sources of miss chance such as blind effects and the uphill miss chance. While the actual chance to evade is diminishing, each source of evasion increases effective HPTechnology company against physical attacks Attack damage is the amount of damage a unit is dealing with an unmodified basic attack; the base values are different for every hero. The total attack damage of a unit is the sum of more than the last due to evasion`s exponential nature. The chances of all sources of evasion are determined by pseudo-random distribution.

Formula:

Miss chance = (1 - evasion from source 1) x (1 - blind from source 2) ... x (1 - evasion/blind from source n) x uphill miss chance

= ⃎ⁿ (1 - evasion/blind_n) x uphill miss chance

Hit chance = 1 - (1 - accuracy from source 1) x (1 - true strike from source 2) = 1 - ⃎ⁿ (1 - accuracy/true strike_n)

Final hit chance = 1 - miss chance + (hit chance * miss chance) = 1 - miss chance x (1 - hit chance)

Final miss chance = 1 - final hit chance = miss chance x (1 - hit chance)

I.e. for Butterfly the chance to get hit is 65% because Butterfly has 35% evasion. The source of evasion values must be expressed in hundredths (so if we have 50% evasion, the value needs to be 50/100 = 0.50).

As an example, if Phantom Assassin has Level 4 Blur (0.5 chance to get hit) and Butterfly (0.65 chance to get hit), her chance to get hit by attacks is 0.5 * 0.65 = 0.325 or 32.5%. A more concrete way of thinking about evasion stacking is that for an attack to bypass an evasion stack and connect, it should bypass each source of evasion in sequence. Only if all sources of evasion fail, is the attack able to deal damage.

Uphill miss chance

The uphill miss chance is a conditional effect, that causes 25% of the ranged attacks to miss if the attacker is at a lower terrain level as the target. It does not matter how many terrain levels difference is between them, the miss chance stays 25%. The terrain level difference of the attacker and the target is taken into account when the projectile hits the target and not when the attacker launches it. Thus, an attack can still miss due to the uphill miss chance even when both the attacker and the target stand at the same elevation level upon projectile launch. Melee units and flying units are unaffected by this and cannot miss due to elevation differences.

True Strike

True Strike is an attack modifier that prevents the affected unit`s attacks from missing, negating evasion, blindness and the 25% uphill miss chance for ranged Attack range is the range at which a hero may perform his or her basic attack on another unit. There are two main subdivisions of attacks: melee and ranged. Attack range can be extended by units. It also prevents melee attacks from missing when the target moves more than 350 range away before the attack. Though, projectiles of a ranged unit with True Strike can still be disjointed Shadow Fiend using a Blink Dagger to dodge Phantom Assassin s Stifling Dagger Disjointing is the act of dodging projectiles, or rather, to cause a projectile to fully lose track of its target. A disjoint is . True Strike does not work when attacking buildings Buildings are special units that are immune to most spells, use structure armor, and are immobile. Destroying a building rewards you with a bounty, similar to most creeps or heroes. Destroying towers rewards the entire . Be that as it may, it works against any other unit, including wards This page is about in-game units. For cosmetic pets, see Summoned Unit. Summons are a type of units that are created with spells. Players do not encounter them, unless they play as, with or against and allied units.

Accuracy

Accuracy works similar to True Strike. While True Strike prevents the unit to miss any of its attacks, accuracy prevents the units from being missed by any attack. Just like True Strike, accuracy works against evasion, blind, uphill miss chance and melee attacks missing when the target moves too far away. The unit can still disjoint ranged attack projectiles.
