If a Wizard loses one or more Wizard levels, they instantly forget a single spell for each Wizard level lost, starting with their highest-level spells. If they know multiple spells of the same spell level, randomly choose which spell is lost unless specified.

A model can lose Wizard levels granted by a magic item. Bound Spells cannot be forgotten if a Wizard loses a Wizard level. If a model has loses a Wizard level and has a selection of "normal" and bound spells, do not include the bound spells when randomising which are forgotten.

If a Wizard has had their level reduced to 0 they no longer counts as a Wizard and cannot attempt to channel Power and Dispel dice. They can no longer cast any spells, except for any Bound spells they might still have.
