Belial by HexerVoodoom

Passive: Whenever Belial is out of enemy sight he will change appearance into archer minion. Using abilities will not break the disguise. Allies will still see him at mini map and a special aura around him. If damaged, mounting, taunting, dancing or hearthsoning, disguise will breake. Revealing abilities such Kilrogg eye and Tassadar`s trait also breakes this effect.

Active: will hide allied icons on mini map for every enemy for 4s. CD 60s.

Belial summons a copy of himself that will mimic his moves, attacks and abilities against same target. This copy can do no damage and will disappear when lose 50% of srtating HP.

Belial will target an enemy and deceive it for 6s. If affected enemy casts any ability during this time, another random ability will be used instead. If used ability requires targeting, an elective target will be chosen randomly. If used ability requires area selecting, the center of this area will be the closest possible of cursor when ability was cast. If ability cast was on cooldown, it will not be cast but instead a fog of Belial will appear above hero and consume the mana of that ability. Affected enemy loses 20 armor.

Could also have a talent to make moving actions go to the opposite way.

Belial will shot a fly swam into a straight path. If the fly swarm encounters enemy unit, will attack; if dont't will search for closest target for it's duration.
Fly swarm will slowly damage any unit/building it is affecting.
If enemy unit/building is killed while it's active, it will jump to another random close unit/building and duration increases by 2 seconds (up to 5). If no new target is aviable for it's duration, will be gone. Fly swarm will be active for 5 seconds.
1s cooldown. Stacks.

Target ability. Active during 10 seconds. If affected hero is support, everything will be seen as allied, and every hero will be seen as himself: affected support hero won't be able to attack or cause damage but will be able to heal enemy heroes, perceived as allies. If affected hero is not support, everything will be seen as enemy and all heroes will be seen as himself: will be able to harm allies and healing abilities will do no effect.

Belial will become a large immobile creature with big HP pool for 20 seconds. Basic attacks will be more powerful and in arch in front of him (AOE, like ragnaros' D swing ). While active, it's trait will change and instead will be a new ability: Meteor Strike (5s CD). Meteor Strike targets 3 equally distanced circular areas that will explode after few seconds, stunning and damaging units (double damage on buildings).
