Magical items can be attached to the champions on phase 3. As long as the card's special power does not state otherwise, it cannot be attached to realms, holdings, allies, or any other card type. A magical item should be placed under or near the champion's card. Champions can possess any number of magical items.
Magical items have either Offensive (Off) or Defensive (Def) markings in their description. Assume that offensive magical items directly affect the opposing champion during combat or in their pool. A defensive magical item is assumed to affect only the champion it is attached to and not the opposing champion. Magically immune champions usually only seem to be immune to offensive magical items.
Any special power of the magical item that would directly affect an opponent, such as its level bonus, is ignored by champions immune to it. When the magical item can affect only the attached champion or his attachments, another card's immunity to magical items would not negate that effect.
Magical items can be attached to the champions during phase 3 only. You can not use them from the hand during phase 4. Champion entering combat from the hand does not have any magical items attached. Some rare magical items negate this rule and can be used during combat. That is written on the card's special powers.
