=Mastery=

There is not simply one degree of understanding for each Rune. An initiate and a Runelord are differentiated not only by how many Runes each possesses, but also how deeply each possessed Rune is understood. This is Mastery. It is gained through experience of the use of the Rune, but also through study and meditation on the purview of the Rune. You cannot gain mastery above five, but Effective Mastery may become higher than five.

Each Rune purchased begins at Mastery 0, which allows the Runes use in spellcasting; however, higher levels of Mastery give Greater benefits. The Effective Mastery of a spell can be increased in many ways, the simplest being simply to have the spell anchored. Other boons to Effective Mastery, such as increasing spells power near a large concentration of an associated element or as part of a ritual (or ritual site) are valid, but largely at GM's discretion.

[Currently, there is no benefit to increasing mastery/effective mastery above 5. There probably will be in the future though, so come up with ideas and share them if you're of the mind to specialize that deeply.]

You may add your mastery rank as a bonus to any knowledge roll where the Rune might be relevant, as your deep understanding of it bleeds over into innate knowledge. A Mastery of the Rune of Gods might aid you in recalling the names of a local Pantheon, while a Mastery of Fire might help you predict and control the spread of a forest fire.

Also, each rank of mastery has specific benefits.
* '''Mastery 0'''
You may use the rune in spells. This is the default level for runes you know.

* '''Mastery''' •
If the Rune fails in a spell (i.e. rolls a 1), you may spend a power point to upgrade it to a 2 (causing it to not fail).

* '''Mastery''' ••
You can spend a power point to increase a Runes dice size by a single rank (A mastery 2 Minor can be rolled as a d6, a mastery 2 Major can be rolled as a d8, a mastery 2 Greater can be rolled as a D10).

* '''Mastery''' •••
You can spend a power point to increase a Runes modifier to the spell total by one, empowering the spell overall and making it more likely to succeed.
* '''Mastery''' ••••
You can spend additional power points to increase a dice size by an additional rank, or increase a runes modifier to the spell total by an additional one. You cannot do both simultaneously, though you can still combine this with the abilities for ranks 2 and/or 3.

* '''Mastery''' •••••
You may use both versions of the rank 4 power simultaneously.

With all mastery abilities, you can increase a Rune roll to prevent failing, increase die size twice, and increase Rune modifier twice, for a maximum of five extra points.

You may use as many benefits of levels of mastery in a spell as you have sufficient power remaining for.

[ex: If you have an anchored spell which includes a rune that you have mastery 3 in, your effective mastery of that rune is 4. Therefore, you may spend power to gain any and all of the 4 possible boons]
