Well the stones whisper to people because they're evil. I believe it happened to Lazarus and a few other people. So to leave a stone like that laying around for anyone to take hold of seems like a bad idea.
As for why he felt he needed to put it into his head, my guess is that if left unattended maybe the demonic energy would seep out into the surroundings and affect others. So he used himself to contain the demonic energy but it was too much for him in the end.
okay here is my question-
in a lore book i read Heaven and Hell were always evenly matched. so how did the Angels match the Demons if the Demons have larger numbers+the Seven Evils? Did the Angles have like a super powerful God dude or something? Is the Angiris Counsel a huge step up in power than an Arch-Angel?
There is no "God" no, but yes the Angiris Council is far more powerful than regular angels and arch angels is my understanding.
why did mephisto hate Inarius so much? what did he do to piss of the 3 prime evils so much that they would strike a deal with the angels so they could torture him? Sry if this was alrdy answered 40 pages is alot to read.
Well Inarius was with Lilith, wasn't that like Mephistos Daughter or something? I don't feel like checking right at this moment.
I used to think that I read that Diablo is the strongest of the Three, while Mephisto is the eldest. But now I cant find the quote to support myself, so I'll just assume that I read wrong. Or maybe I was just thinking of that quote from Astrogha. I dunno, its debatable. He may be slightly stronger than the others, but likely not by much.
Thats kind of how I think the angiris council is also. They all have slightly different levels of power, but are pretty much equal.
Their essences are immortal...hence..cannot be killed. They can only be sent to the Abyss (where they come from) or to the Void (which is described as complete nothingness (but they can return from that as well like we see with Lilith.
Lilith came back?
Are you talking about when you kill her on Bnet on D2? I heard that wasn't canon.
