Unless stated otherwise, such spells are not cumulative and casting them multiple times will have no further effect.

The Warhammer world is an intrinsically magical place. In battle, magic is a force as real and potent as a sword blade, its use limited only by the imagination and skill of the Wizard that wields it. Magic can be a subtle force, infusing allies with strength and valour, or enemies with frailty and dread. More commonly, however, Wizards unshackle the raw power that lies at the heart of magic's chaotic nature, summoning hungry firestorms or devastating bolts of eldritch power. It is therefore only right that magic should form a core part of the game of Warhammer: the Old World as well. Wizards are able to cast spells of different types throughout the turn, and players must protect them accordingly, ensuring they are able to cast the right spell at the right moment, or to thwart the casting attempts of their rivals. That being the case, explaining how magic works early on is important and the following sections do just that. New players can skip over this section for now if they wish, focusing instead on the more mundane rules and returning to this section once a few games have been played.

Magic

A roll of 8 or higher on the Miscast table affects all friendly Wizards.

No. A roll of a natural double 1 isn't merely a failed Casting roll, it is a Miscast, as described on page 109.

No, your casting result determines the 'strength' of the spell. In other words, the higher your casting result, the more power the spell will have and the greater its effect will be.

If the Wizard is within range of the model casting the Bound spell and not otherwise prevented from attempting a Wizardly dispel, yes. As stated on page 109, you may attempt to dispel a Bound spell as usual.

Yes. Whilst such attributes are as protective as a suit of armour, such models do not wear armour.

They only need to be within the fighting rank.

Yes. Magical vortexes are considered tall enough to affect even models that are flying high above the battlefield.
