He exaggerated, the power is called Burning Alignment...
In future, if something sounds too good to be true, just ask him to show you where in the book it is
Probably more me not remembering it properly. Just wanted to make sure it was real :p
I didn't mind, even if it was fake, seeing as how he threw it at my STank (yeah I take one in 1500 points in my competitive list, what you gonna do
), so I just avoided it with the rest.
Kept my unbreakable GS unit in the watch tower (with lector/mace of helstrum) for 3 turns before putting in my 35 unbreakable halbs (with WP) in. Needless to say I won, but he was excited he killed my stank with his steg, 25 sarus and 12 skinks. I told him he should hve only thrown the warriors at it and used the steg to kill my infantry, but ah well :p
Couldn't find it in my book though, albeit I got 5 army books for $10 of eBay for the fluff so it might not even be the newest version.
