HESW: Jacob Cross [Death Mask MK.1]

Using one of many abilities from the Shadowed One
This is the black serpent "Death Mask", this creator is made from blood and darkness, these serpents are apart of Jacob now, they can appear from the shadows from he's feet, a flick of he's wrist, to he's very back. He can summon as many "Death Mask" at once, but there a limit, at her current level, he can only summon up to four. Also, I added another one of he's abilities "Crimson Claw" X3

[Hint 1: Jacob's eye's only turn blue to show he has full control of he's dark abilities]
[Hint 2: He's arms never turn complete black during daylight hours]
[Hint 3: There was about 3-5 Cores used to create this abilities]
