Spell Savant (Aspect)

You’ve narrowed your specialization in spellcasting to a single spell, which you have developed an obsessive expertise with.

Select one spell which you know with the same school that you selected your Spell Specialization in. You gain a +1 bonus to your spell attack rolls and spell save DC when casting that spell. If the spell does damage, it deals additional damage equal to a roll of your Mastery Dice.

Special: You may select this Aspect a number of times equal to your Spellcasting Ability Modifier. Its effects do not stack. Instead, you may choose a different spell.
