The only change in this version of the Warhammer FAQ (1.5) is Power Scroll, which now reads:
Reference Section – Arcane Items, Power Scroll
Change to “POWER SCROLL 35 points
One use only. A Power Scroll can be used when the Wizard
makes a casting attempt. During that casting attempt, the
casting value of the spell is halved. You cannot choose to boost
a spell when using the Power Scroll.”
A big change indeed, as it makes it useful and not completely OP - thereby making it legal in tournaments again!
