A Holy Symbol is a Casting Armament which requires Devotion to use. Holy Symbols do not have Quality benefits- instead, they gain additional, cumulative benefits as conditions are met (in this case, having a certain number of appropriate Glyphs Attuned, based on the character’s Deity). A Holy Symbol must be at least 1 foot in diameter and in-hand to benefit from. 

2 Glyphs: While wielding a Holy Symbol, the character may substitute 50% of an Active Mana Cost for Focus when casting Light or Void Spells. 4 Glyphs: The Character is Immune to Interruption from damage while casting Light or Void Spells.

 6 Glyphs: The Character may Auto-hit Light or Void Spells up to Empowered Rank within 10 feet. Auto-hit Spells may not be Instant Cast. 10 Glyphs: All Active Light and/or Void Spell Glyphs gain +1 Scale.  

A character devoted to a Void Deity must have the appropriate number of Void Glyphs Attuned, or Light Glyphs for one devoted to a Light Deity.

 In the case of a character devoted to Aramil, the number of required Glyphs is 50% of each type Light and Void.
