Spell Mastery

From Project: Redcap
(Redirected from Mastery Ability)

Spell Mastery represents a way to focus on the perfection of a particular formulaic or ritual spell.

Spell Mastery Ability

In ArM5, Spell Mastery is a special family of Abilities. There is one Ability for each formulaic or ritual Spell.[1] Magi can learn Spell Mastery in the same ways they learn any other Abilities: for example, from books.[2]

Benefits

The Spell Mastery Ability adds to a magus's Casting Total when he casts that spell, and decreases the number of botch dice he must roll, possibly decreasing the botch dice to zero.[1]

In addition, for each level in the Spell Mastery Ability for a particular spell, the magus gains one special ability he may use in casting that spell, making its casting easier, more powerful or more convenient in some significant way.[3]

A Note On Terminology

It is easy to confuse the terms when learning about Spell Mastery. There are three related concepts that should nonetheless be clearly distinguished from each other.

The Learned Spell (Formulaic or Ritual)

In Ars Magica Fifth Edition terminology the spells proper are not considered Abilities. They must, of course, be learned (individually) before Mastery can exist. It is possible and in fact usual for Magi to know a number of Spells that they have not Mastered.

The Spell Mastery Ability (for that specific Spell)

Or simply Mastery Ability. It is learned (and bought) separately for each Spell. As noted above, Mastery of a specific spell adds to the Casting Total and reduces the number of both dice applied, potentially removing them entirely. In other words, Mastered Spells are more powerful, safer and more reliable than they would otherwise be.

Each Mastered Spell will have its Mastery bought separately, quite often with varying levels of Mastery for different spells.

Most Magi will also have a number of Spells that they have learned but not Mastered.

The Mastered Spell Special Ability

The operative word is Special; Mastery goes beyond simple efficiency and reliability and always confers at least one special benefit to Casting.

These Special Abilities are not bought separately. They exist as a special effect and benefit from each level of Mastery for a specific Spell, and are paid in full by the Mastery Ability itself.

It is possible and in fact usual to have several simultaneous such benefits for a single Spell, as long as the level of Mastery for that Spell exceeds 1.

Different Mastered Spells can (and very often do) have wildly different sets of Special Abilities, even if they have been learned by the very same Magus.

Mastered Spell Special Abilities

The following special abilities are available to any caster:

Example from ArM5

The core Rulebook for Ars Magica Fifth Edition presents an example Magus, Darius of Flambeau. Darius has the Flawless Magic Virtue described in ArM5 p. 42, and for that reason every single spell that he has learned is automatically Mastered to at least Level 1.[4]

Darius has an unusually high number of learned (and in his case, Mastered) spells for a starting character - well over twenty. His character concept gives him priority to efficiency in combat situations,[5] and therefore many of his spells are based on the Perdo Technique and Mastered with either Fast Casting or Penetration among their Mastered Special Abilities.[6]

There are however exceptions; a few of his learned spells have instead the Mastered Special Abilities of Quiet Casting (sometimes taken twice for the same spell) and Magic Resistance (sometimes combined with Penetration for the same spell when the spell has been learned with Mastery 2 or higher). A couple of spells have been learned with Mastery 3 and taken as their Special Abilities Quiet Casting x 2 and Still Casting.[7]

Spell Mastery in Previous Editions

Mastered spell special abilities were introduced in ArM5. In previous editions, spell mastery existed, but the rules didn't confer any special variations on the effects of the spell
