hope this helps ^_^ it's pretty easy to get them if youv'e finished the area no bosses
but you should be at level 75 when you fight abyssion (it took me a half an hour to kill him >_

Well, with your question, you said WHAT are the devil's arms. They are the weakest, but most dangerous weapons used by Lord Nemblim himself. There also used poorly by Abbyson (yes, poorly. Srry to say that).

They are the evil weapons of the dark lord Nemblim. They have pretty weak stats but I hear that their strength increases with the amount of monsters you kill. So if you like killing thing they're the perfect weapon for you.(And I agree with cheatersGuy they were used terribly by Abbysion in our half hour fight to the death. And he also knew all our techs. That's pretty sad now that you mention it.)
