Rune of Power

Uncommon Rune

When you hit any Attack, you can use your Reaction and deal extra 3d8 force damage.

Runes

Runes are magical signs inscribed in an equipment, which can be used to activate a magical effect. Once a Rune is used, it disappears and it cannot be used again. A creature can only carry 1 Rune, which must be inscribed in an equipment which it is attuned with in order to be used.

With 3 hours of work, you can inscribe Runes in any equipment by using Magical Gems. When you do so, you must make a Check using the Tool’s skill (Arcana or Tools Manipulation).

If the result is equal or higher than the Check DC on the Spellcraft Table, you succeed and you then inscribe a Rune with the same rarity as the Magical Gem used. On a fail, you waste the Magical Gem instead.
