Used a 25 gem violet orb 13 emeralds and 3 each of the other all lv10. Figured this guy would be a great addition to the team. Hope he grows nice and strong lol.
Use him on a team with a Fallen Carnage and a Raven Acolyte. The Raven reduces everything to half health, the Carnage eats the weakest member, splashes damage to the rest of the enemy team, and every kill he gets weakens his next victim(s). Then your Devil can mop up.
