Mastered Spell Special Ability

In ArM5, Spell Mastery is a special family of Abilities. There is one Ability for each formulaic or ritual Spell.

For each rank in Spell Mastery, the magus may choose one special ability that improves the way he can cast that spell. Each special ability offers a different benefit, usually a variation on the standard spellcasting rules.
