You have the ability to cast a spell. This trait is always granted by another trait, that will specify which spell you have learned, what Spellcasting Skill is required to cast it, and what Spellcasting Attribute is used for this spell.
You gain a number of points of mana equal to your level. If you have mana from any other source, add this additional mana to your usual source. The cost in mana to cast a spell is equal to the Power of the spell being cast.
Whenever your party rolls initiative, if you have less mana currently available than your level, increase your current mana by two, to a limit of your level.
