(Character Concept) Teny, the Darkin Twin-Daggers

I have been thinking about what could be next darkin. I came up with idea of duality between two darkins fighting over body of a weak human mage.

Teny could be played on AP or AD depends on sister in control. However I would mostly prefer hybrid build because which sister is in charge can change multiple times over game. Gathering power should be a little bit faster than it is with kayn.

With maxing W, he could be played on lanes. And with maxing Q, he could be a nice jungler.

Teny, the Darkin Twin-Daggers

However with each use of Blade of Naara, Naara is closer to control Tenys body. Whichever sister gather more power first, she will gain instant control over Teny’s body.

When Regana gains control over body, Tony gains bonus 10 - 40 Bonus Attack Damage (Based on level) When Naara gains control over body, Tony gains bonus 20 - 60 Ability Power. (Based on level)

R: Unity CD: 60 Mana: 150/200/250

For 6/9/12 seconds all three entities merge into one, transforming Teny into powerful being. Tenys passive and abilities are upgraded by influence of both sisters and tony gains bonus 10/15/20% CD reduction until end of unity. This cooldown reduction can temporarily excess maximum cooldown reduction.

After Unity ends, sisters has no control over Teny’s body and they needs to gather enough power to take control over him once again.
