Diablo Clone in 1.10

i went onto a forum from battle.net and found a mod for single player that makes the diablo clone appear in the blood moor. i killed him in hell difficulty and he dropped annihilus. He is very hard my zon did about 20k and it took 5mins of arrows to kill him. anyway if anyone would like to try and fight him like i did and i dont know if this is on any other threads but pm me and i will send you the mods to make him appear or someone can tell me if it is ok to post the mods in this thread. thanks
