Evasion

Evasion is a passive ability that gives the unit a chance to dodge an incoming physical attack. However, True Strike granted by Monkey King Bar will completely negate all evasion effects, except against towers.

Multiple sources of evasion stack, 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 will have the same effectiveness regardless of how many there are. Evasion does not use pseudo-random distribution.

Faceless Void's is notable in that it is not considered Evasion.

Evasion stacks diminishingly, so we have:

Total evasion percentage = [ 1 - (1 - first source of evasion) x (1 - second source of evasion) ... x (1 - n-source of evasion)] x 100

The source of evasion values must be expressed in hundredth (so if we have 50% evasion, the value will be 50/100 = 0.5).

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, will the attack be able to deal damage.
