Wizards wear little or no armour even in the thick of battle, as large amounts of metal upset their magic harmonics and inhibit the use of their powers. Instead they are likely to be protected by powerful spells and magic items. Many wizards wear decorative vambraces, wrist bands, and smaller pieces of armour, but this is insufficient to warrant a saving throw or to affect their ability to cast spells.

A wizard mounted as a cavalry model may ride a horse with barding armour without affecting his own ability to cast spells. Otherwise a wizard wearing armour may not cast spells, not even spells that are bound within a magic item. This does not stop the wizard using other magic items however. The exception to this rule is Chaos armour, which is saturated with magic, and does not therefore prevent a Chaos Sorcerer casting spells (see the separate Warhammer Magic supplement).

The complete rules for wizards, spellcasting, and many magic items are covered by the separate Warhammer Magic game. We have included a selection of magic items in Warhammer to give players a taste of what it is like to use magic. Refer to the Magic section of the rulebook for a description of how these work.
