New Champion Idea!!!

I was on Youtube and i saw a video of a World of Warcraft player playing a character Blizzard calls, "Death Knight" so i looked up more videos of them and i think Riot could do something along those lines, I think a good name could be Valcorie, kind of sounds like its own version of death in my opinion lol, anyway! His ult could be a 2 minute cool down and be called Death Grip which will grip the enemy to the "Death Knight" or Valcorie and leave a foot or two of space in between the target and Valcorie, giving the opponent a fighting chance, maybe have a move or two called Festering Strike or something along those lines where it will give the enemy player a DoT (Damage Over Time) debuff that will damage a portion of the enemies health (Damage Amount Will Depend On How Player Builds), maybe possibly even a AoE (Area Of Effect) move that will affect all players that stand within this circle possibly? But i think the colors of his armor should be possibly black and a light blue possibly a teal that has a glowing affect, i personally think it would make an awesome character! Link will be in the description for the armor colors! There are so many possobilites that could go into this character!
