Runes

Runes are enchanted stones imbued with lyrium and arcane energies. Runes improve the effectiveness of weapons and armor, and can be applied by a Dwarf or Tranquil Runecrafter. The process of applying a rune is called "enchantment." Once a rune is applied, it can be removed or replaced by a Runecrafter.

Weapon Runes
In addition to a rune's effects, you also gain access to a special stunt associated with the rune type. These special stunts are only available while wielding the weapon to which the rune has been applied.

*Blessed Rune's effects require the character to have faith in some Divine entity.

** Blood Runes are not widely available, as they are very illegal in most places in Thedas.

Armor Runes
Armor runes can be applied to certain armor to provide bonuses to that armor's effects. Body armor can support up to two runes simultaneously, while a helmet can only have one. (A player's entire armor set can only have up to three runes total.)
