Doppleganger

Doppleganger

The control hero who actually lives up to his name. He's a very unique hero, being able to turn into an enemy hero, and not only that, but being quite a dangerous foe even without transforming. 

Skills:

Doppleganger's special (the one he is most known for), transforms himself into any chosen enemy hero on the battlefield (Except for Unstable heroes like Understudy). If ran on auto, Doppleganger will transform into a random enemy hero. When he transforms, he gains a certain amount of health and 750 energy and removes all DoT effects that were placed on him before. He attains all of the skills of the hero he transforms into, including the legendary skill (even if Doppleganger isn't orange yet), setting the skill levels to the level of the special. He doesn't take over the targeted hero's rarity, however. His green skill targets the foe with the highest strength (mostly frontline tanks), reducing the target's armor by a certain amount and blinding them for 7 seconds. This skill triggers usually after every basic attack. After transforming into an enemy hero, the skill grants Doppleganger the same amount of armor as it takes away from enemies. This is useful against heavy damage tanks like Roller, Revenant, and Megataur. Doppleganger's blue skill summons a mini version of himself, which runs up to the closest enemy hero and splashes itself onto surrounding foes, dealing a hefty amount of magic damage. The mini version has a certain amount of health and can be targeted by enemy heroes. If killed before reaching an enemy hero, the mini will burst on the spot. After transforming, the blue skill will grant him a certain amount of magic resistance. Doppleganger's purple skill gives him expertise, increases the level of Doppleganger's skills. This means that if Doppleganger has 10 expertise, then the rest of his skills will be bumped up 10 levels. A level100 white skill would actually have the effects of a level110. It's very good on his special, as it'll set all copied skills to the skill level of the special added with the amount of expertise Doppleganger has. Copying Medusa or any hero that depends on skill level would be most useful.

Rune Sets:

 

Tree, Rock, Mist are recommended. It seems unusual, but looking closer, it's not. Both his green and blue skills give Doppleganger extra armor and magic resistance. He's not a fragile hero either. In addition to that, Tree Rock Mist are the runes that can factor into literally almost every hero that he copies (Except for Spectral Drake, Rock doesn't do anything for him). But now that I think about it, River would be astounding on Doppleganger. It'll get him transforming faster, he gains more energy when transforming, and he plainly just gains more energy while in transformation. 

Rune Bonuses:

Max Health, Magic Resistance, Armor, Skill Power, Tenacity, Fury, Magic Pen, Water Damage, Accuracy, Expertise, Longer Disables, Starting Energy

Unnecessary, but do have a positive effect bonuses:

All other bonuses (for when copying all other heroes), like Armor Penetration (Only when copying a physical attacker), all other damage subtypes (Bashing, Piercing) (For when copying any hero with different subtypes), Improve Healing (Copying Healers), Life Steal (Copying heavy physical attackers)

Ending Note:

A very unique hero, may have some usage in the future, but won't be prevalent now.
