Click any of the column headers to sort spells by that column. You can filter spell classes by clicking on the class name.

The minimum level is the lowest level of the specified magic skill class that is required to use the spell; The minimum mana cost is the mana cost required to cast the spell at the minimum/required level. Similarly, the maximum mana cost is the that which is required for the maximum spell level.

Once your character passes the maximum spell level, the spell will cease to increase in both mana cost and effects (damage, bonuses, etc).
