Dota 2 butterfly evasion 7

Evasion

is mechanic that allows the unit to dodge an incoming attack. When evaded, the attack gets completely nullified. This means, anything that relies on attacks to hit their targets do not trigger, which includes most attack modifiers, and on-hit effects.

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 gets completely nullified.

Mechanics [ edit ]

Evasion and blind trigger upon landing an attack, which is on projectile impact for ranged units. If it triggers, the attack does not affect the evading unit at all, 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 [ edit ]

Multiple sources of evasion stack multiplicatively with each other, while sources of blind effects stack additively with each other and multiplicatively with evasion. The uphill miss chance stacks multiplicatively with evasion and blind. While the actual chance to evade is diminishing, each source of evasion increases effective HP against physical attacks more than the last due to evasion’s exponential nature. The chances of all sources of evasion and blind are determined by pseudo-random distribution.

Formula Miss chance = 1 – [(1 – evasion from source 1) x (1 – evasion from source n) x (1 – (sum of all sources of blind)) x (1 – uphill miss chance)]
= 1 – [Π n (1 – evasion_n) x (1 – Min(sum of all sources of blind, 100%)) x (1 – uphill miss chance)] Hit chance = 1 – [(1 – accuracy from source 1) x (1 – accuracy from source 2)] = 1 – Π n (1 – accuracy_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)

E. g. 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.
