If a spell from the Lore of High Magic is successfully cast by a Wizard from Warhammer: Lizardmen, the caster can choose to forget that spell at the end of his Magic phase. At the end of the Magic phase, the Wizard must immediately generate a replacement spell from any of the spell lores he can normally use for each spell forgotten in this manner; generate the spell in the normal way. If the Wizard chooses to generate a spell from a different lore, that newly generated spell will always use that spell’s lore attribute. It is also possible that the Wizard might generate the same spell he just forgot, or one forgotten in a previous turn (for whatever reason).
