Remains in play. The caster metamorphoses into a shrieking, taloned creature of Kislev legend, carried across the battlefield in a whirlwind of purest cold. The caster may fly whilst this spell is in play. In addition, the caster has Strength 5 and Attacks 4. The effects of all equipment, including magic items, steeds and weapons, are ignored for the duration of this spell, as they are transmogrified along with the caster. The Form of the Frostfiend continues to work until it is dispelled, or until the Wizard chooses to end it (which she can do at any time), attempts to cast another spell or is slain.
