Chapter 11: Crafting & Treasure / Runes

Fundamental Runes

Source Core Rulebook pg. 580
Four fundamental runes produce the most essential magic of protection and destruction: armor potency and resilient runes for armor, and weapon potency and striking runes for weapons. A potency rune is what makes a weapon a magic weapon (page 599) or armor magic armor (page 556).

An item can have only one fundamental rune of each type, though etching a stronger rune can upgrade an existing rune to the more powerful version (as described in each rune’s entry). As you level up, you typically alternate between increasing an item’s potency rune and its striking or resilient rune when you can afford to.
