Illusions



Illusions are imperfect, weaker copies of heroes, created by abilities or items. They look like and are mostly treated like a hero, but are impaired, as they usually have incoming and outgoing damage penalties, dealing less damage and taking more damage than heroes. They are incapable of casting abilities or using active item abilities, and also have some passive abilities disabled. They also may not drop or pick up items or runes. Illusions yield a little gold and experience based on the hero's level. They do not soak up any experience and gold. Illusions cannot level up, the gold from last hits they make goes to their owners, and do not interfere with kill streaks or counters.

Illusions can be created from an allied, enemy, or the own hero. The illusions copies its appearance, level,, attack values, defensive values (e.g. base armor and base magic resistance) and abilities on their current level. All items owned by the main hero are copied as well, including all their stats (although some effects of abilities and items are disabled for illusions).

All illusions deal % less damage against buildings, making them weaker in pushing. This reduction stacks multiplicatively with the outgoing damage reduction values most illusions have, and also multiplicatively with the damage reduction hero damage does against structure armor type. However, due to the fact that illusions are based on heroes, their damage scales together with the heroes, making them still a significant pushing tool, especially in later phases of a match.

All illusions are invulnerable for 0.1 seconds as they spawn, regardless of which ability that spawns or creates them. Illusions also always play the same spawn sound upon spawning, which are only audible to allies, and the same death sound upon dying in any way, including upon expiring.

Visual Appearance


Illusions are always visually distinguishable to their allies, with an extra texture layer on their model and their unit portrait, and a creep health bar. Allied Illusions also have a duration indicator the left of their health bar.

For enemy illusions, this depends on the source ability. Some abilities create illusions that the enemy also sees as an illusion, with the extra texture layer and a creep health bar (but without the duration indicator), however, some other abilities create illusions that are camouflaged.

To the enemy, a camouflaged illusion looks identical to the hero they are based on. They do not show their illusion texture, and display the regular hero health bar with all its components (hero icon, player name, mana bar, other extra icons like the Battle Pass badges). Allies see them as illusions normally.

There are 7 different illusion textures.

Bounty
Illusions have a gold and experience bounty equal to two times their level. The gold bounty is granted to the player killing the illusion, while the experience is shared within the default experience area. However, the experience is only granted when the illusion is killed by a player. Expiring illusions, or illusions dying to lane creeps, towers, fountains or neutral creeps do not grant any experience.

Illusion bounty formula:

The following table shows their bounties on each level:

Active Abilities
Illusions may not use active abilities and items, but they might inherit ongoing abilities from the original hero if the ability was cast before creating the illusion. Only a few abilities have different effect when the cast is an illusion.

Casting Fake Abilities
Within a certain conditions, some abilities causes all illusions owned by the illusion creator within certain range from the target will also fake cast the ability, while the real hero casts the ability.

This is mainly for camouflaging the real hero and their illusions. The illusions still cannot use any active abilities.

These illusions have the following behavior:
 * The illusion play the whole cast animation and cast the fake ability at the same time the real ability is cast.
 * When illusions currently are not having any order and are standing still, they all turn to face the target and cast the ability.
 * When canceling the cast (S), the illusions still play the full cast animation, but do not release the fake ability.
 * When illusions are moving or attacking, they continue to do so and do not turn to face the target. They still play the cast animation, overriding their move or attack animations.
 * They play the whole cast animation and release their fake ability at the same time the real ability is released.
 * These fake abilities do not interact with anything.
