Ok so this is literally a new champion so people dont know much on him but I've played about 15-20 games now with him and I have found that hes almost like another Master Yi except all his health regen comes from basic attacks.

At about the time that you aquire the items Blood Thirster and Blade of the Ruined King you can stop using "Blood Thirst" as often and use "Blood Price" more b/c your going to be getting pretty much 2x the amount of health lost for "Blood Price" back just from your Life Steal, but otherwise i use "Blood Thirst" until then.

I've found that is Blood Well can be super OP specially when ever facing multiple opponents. Keeping Aatrox's "Blood Thirst" and "Blood Price" capped first will keep u alive and you can just use "Dark Flight" to dodge spells and escape as well as using "Blades of Torment" to slow your enemy for that final blow or keeping a ADC in a group fight.

Somethings that people think are glitchy about his "Dark Flight" are that if he casts his spell and a snare is cast on him that snare wont activate until after he has landed for instance Zyra's Grasping Roots or if the "Dark Flight" spell is cast at the same time as Xin Zhao uses his Crescent Sweep and Aatrox is pushed back "Dark Flight" will activate after Xin Zhao's attack. Dark Flight was intended to be this way this spell is not glitched in any way.

Spells that can be dodged by Dark Flight are of Course any spell that isn't a Lock target spell and it can be used the same as Alistar's Pulverize and Malphites Unstoppable Force to cancel a Players attack.

Ok so ummm this is what I've gotten out of this Champ so far I'm sure I'll update at a later time and add some more things and if u guys have any other suggestions feel free to let me know and I'll add them in.
