Some friends and I are looking to restart our intermittent gaming group with a spot of Realm of Chaos warband gaming. I've rolled up my Tzeentch warband, ready to collect/convert/paint for a proposed game over Christmas (baby steps!). Anyway, I rolled "hell shafts" as my magic item but I can't find the rules for them anywhere
Admittedly my RoC books are of the, erm, electronic form and I know there's a dodgy section in my Lost and the Damned so perhaps it's lost in the digital fog.
tl;dr version - what are the rules for "hell shafts", please?
