These symbols convey protective forces from the Elemental Planes. You gain resistance 5 to acid, cold, electricity, or fire. The crafter chooses the damage type when creating the rune. Multiple energy-resistant runes can be etched onto a suit of armor; rather than using only the highest-level effect, each must provide resistance to a different damage type. For instance, a +2 acid-resistant greater fire-resistant breastplate would give you acid resistance 5 and fire resistance 10.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
AbjurationEffects and magic items with this trait are associated with the abjuration school of magic, typically involving protection or wards.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
