'Ello there... once again! You're just putting all these concepts up today, huh? Well, anywho, I must say I'm a bit confused about this kit you have going on here. I can't seem to get a clear picture of his Q, is it like an Ahri W or...? I'd appreciate it if I could get some clarification behind that before I go into further detail with this.
By the way, there's no numbers :D Which is of no issues, as I didn't use them myself when I posted champion concepts way back in the day (I only did two mind you, and only one of them I could say I'm proud of), but that's not the point. I'd appreciate it if you could tell us what KIND of damage does he do? Does he like to deal physical, magical, hybrid, or even true damaging people because hey, why not?
Ah, his E, how must you dare to exist. I'm joking, naturally, but I can't seem to find a place with it in his kit. He's a fighter and a tank, and last I checked armor doesn't go around carrying mines normally, but I could be wrong. In all seriousness though, I don't believe that a trap is the best option for his kit.
His ult reminds me a lot of Gnar's, which is unfortunate because an armor wraith could have some really cool ults with unique interactions... I just can't think of any at the moment. Also, where would he get a large plate from? Don't tell me he's larger than a Cho'Gath, as I'd have to wonder what blacksmith felt the itching to make that armor.
Speaking of making armor, I must say I'm curious about his lore. I'm sure all of us having an armor wearing wraith in our basements, but how did he end up to being... well... himself. Don't forget about that title by the way, it adds the epic to epic in a champion. :D
Finally, I'm just going to address his kit as a whole. (I'll just mention now there be passive now.) I feel like his kit really misses out on the whole haunted armor kind of situation, where the armor could be breaking apart, coming back together, all that fun stuff. That's just my opinion though.
Good luck with your champion ^.^
