Mal'Ganis by Omnidus

Level 1

Blood Orb
Regeneration Globe and Healing Fountains heal twice as fast.
Collecting Regen Globe will grant 1 charge of Blood Orb, up to 3. Spend 1 charge of Blood Orb to grant the HP regeneration effect of a Regeneration Globe. Activated with Trait (D).
Quest: Each Regeneration Orb collected increases the healing of Blood Orbs by 1%.
Note: Blood Orbs do not count towards Regeneration Globe quests, nor are they increased by Regeneration Orb effects like Diablo's level 1 talent.

Level 7

From the Shadows I Come
Burst into a cloud of bats and travel forward with the Carrion Swarm, reforming at the end of the spell. Use Active-1 to cast a normal Carrion Swarm.
The active shares a CD with the new Q - like Stitches' Helping Hand.

Wing Buffet
Increase the size of Carrion Swarm by 40%. The force causes Mal'Ganis to dash backwards.
Small displacement, a little farther than Tychus' scoot. Can be useful to damage enemies while escaping.

Impeding Pathogen

Level 10

Inferno
100 Mana. CD: 120 sec. Call down an inferno to target area dealing 50 (+4%) damage to all enemies and interrupting them on impact. Enemies in the center of the impact take triple damage. An inferno then emerges from the meteor to bathe your enemies with fire for 20 sec. Inferno has 30 Armor to Non-Heroes, Immolation Aura, and can be directed with R.

Corpse Puppet
70 Mana. CD: 75 sec. Enter the corpse of a fallen hero, reanimating a copy of them for 15 sec with 75% HP and granting all basic abilities. Damage and Healing is reduced by 25% of the original hero. Upon expiration or death of the reanimated hero Mal'Ganis is released as an invulnerable shadow from the corpse for 1 sec after which he reforms as his true self. Can be released early by reactivating R.

Dark Arcanist

Have him shoot little purple-ish shadow trails for the ranged attacks. Still more vicious in melee.

From Me
1st Hero Concept. Tried to make him a specialist that can provide some minor support to the team, push, and provide some nasty CC that the enemy will have to deal with. Also, I think the talents open up some varied play styles. Not too sure about the functionality of his second heroic - I think it was a cool theory, but hard to implement w/o making it too strong or lackluster. Anyway, let me know what you all think!

Special Mounts?
He could flap his wings and have some shadowy stuff I guess... or we can show off all our fancy mounts and color matching!

Skins?
Obviously his green variation from WC3.



Maybe some sort of Xerxes type stuff from 300 - with wings and all the nipple rings. :-)



A robot transformer type thing to fight Tassadar's sweet fighter jet skin?
