This might be an interesting hero for you.
Name : Mage Orange Model : High Templar/Dark High Teplar (Dark preferred if not taken) Type : Summoner
Passive : Portal Opener - Mage Orange is invulnerable and untargetable when he has an Elemental assisting him.
Special Abilities :
Wrath of the tides : Summons a water Elemental (Archon actor tinted blue) . This elemental will assist Mage Orange and its attacks slow the target.
Rage of the volcano : Summons an Earth Elemental (Archon actor tinted orange). This elemental will assist Mage Orange and its attacks deal AOE damage.
Strike of the thunderstorm : Summons a Storm Elemental (Archon tinted yellow) This elemental will assist Mage Orange and its attacks deal DoT.
Mage Orange has no attack, so when upgrading you pick which Elemental path you want to upgrade. The Elementals will of course be seperate units :P You may pick what attacks , abiltities , stats etc the Elementals have, I wanna see a summoner hero :D
