Wizards can only cast the spells which are listed in the currently equipped grimoire, and a single grimoire can only hold four spells of each level. For any given spell level, wizards have potential access to more spells than any other caster class, but their access at any particular moment is always limited by their current grimoire. You can switch between grimoires during combat, but doing so disables spellcasting for a short while. You can rearrange your spells/grimoires whenever you like (outside of combat) and once you have learned a spell, it's available to use in as many grimoires as you'd like.
If Wizards come across a spell in an enemy's grimoire, they can choose to learn that spell for the cost (in copper pieces) required to research it. However spells learned this way cannot be used if they are beyond the wizards current ability level.  Wizards also learn one or two new spells when they gain a level, but they can't choose to learn unique spells on level up.
These grimoires contain unique spells that cannot be obtained by levelling up.
