Man, I've had a ton of weird questions like that before, wish I had saved them. As for this one, I have no clue, but this thread is a good idea.

No, it can't be wished for, and no it doesn't disappear. You probably got a mirrored valpurium sword (was it flaming?), which is not the same. There is only one Justifier, and Petrus owns it, and the only way you can get it is by killing him. Even becoming Valpurus's champion only gets you a "valpurium sword", not quite the Justifier

I imported the old forum-related pages

I saw all those Bios and had no clue wtf they were so I started deleting them. Only later did I see they were part of forum-related. Want me to put everything back up? Seemed to me that all of the forum-related pages were pretty old and incomplete. I think it'd be awesome to start the communal IVAN game going again

I just imported the old Wiki onto this one.

For those who are editing the Wiki
http://www.attnam.com/wiki/index.php/Special:Ancientpages
Everything before Dec 2007 is unique to the old wiki. Everything after Dec 2007 is either unique to the new Wiki, or there was an article on BOTH the old and the new, and the old article is hidden in the revision history somewhere (overwritten by our new one). So if you're stuck on an article, just check the revision history, and it's possible that somebody wrote something good on the old one.

Mjolak fucking rocks. Every single one of my victorious characters has wielded Mjolak. Get some kick ass limbs and dual-wield adamant Mjolaks enchanted +10 and you will own everybody's soul

Somebody create the gifs / pngs and post them here. I am IVANless atm and can't make them myself

Thunder hammers are pretty kick ass against most monsters as long as you're careful about angles. I'm pretty sure you can calculate the path it's going to take. For example if you are "@" and the monster is "F" and the walls are "#"

@ #
 F#
###

You don't want to hit the monster because the bolt will bounce off of the corner of the walls right back at you. But in this scenario:

@ 
 F
###

You're safe because it'll take a 90 degree angle off the wall.
I'm not entirely sure about that but it does seem to be somewhat predictable.
And anyways if you have sufficient electricity damage it probably won't hurt you (though it may still break your equipment)

you sure about that atomic? I thought they disappeared because they were mirrored items. So you couldn't sell them either

Enner is fairly easy as they say. You just need to detect his flesh, teleport near him, and then usually 2 fireballs will finish him off.
