Description: The unit knows X Learned Spells, chosen from the list of available spells in its unit entry, is a Wizard and if X is 2 or more it also gains Channel(1). The unit may only do a Hereditary Swap if it could have picked the Hereditary Spell during 1.B.a Spell Selections. It is always eligible for a Universal Swap. See Battle Preparation chapter for details.
Despite the whole unit knowing spells only one model is a Caster. Just before choosing targets for a spell, select one Rank-and-File model as the Caster for this spell.
When a Wizard Conclave suffers a Miscast, treat the entire unit as the Caster.
