Welcome to Librarium Online!
I'm bored, I'm sitting here with the pre-release codex and I remember how bad I wanted to know things before I got it..
Is there anything you want to know, just ask.. I will answer as much as possible without violating IP.
I'm an Imperial player who's heard that "Doom will stuff me into a box called pain".
Will it? what does it (roughly) do?
Nominate one enemy unit, all rolls to wound get a re-roll..
What??? Cast on a banshees target, and... mmm... roasty toasty power armor... mmm...
5th? Cool. WotLK? Also cool.
Hate to say it, but this is, at the very best, borderline rules... you really shouldn't be giving these things out in the first place. So, I'm just going to go ahead and close this thread - people's questions will be answered when the codex itself is released.
