When a Rune Fencer uses one of his or her job abilities under the category "Rune Enchantment", then they gain a special status corresponding to that rune and are said to be harboring the rune. A Rune Fencer may harbor up to three runes at a time, and they may freely choose which runes to harbor up to this limit.
Each of the eight runes is associated with one of the eight elements. A Rune Fencer with harbored runes deals elemental damage of the rune's element on their melee auto-attack rounds as an added effect, and has enhanced resistance against attacks whose element that the harbored runes are strong against.
| Icon | Name | Element | Strong vs. |
|---|---|---|---|

Ignis | Fire | Ice |
|
Gelus | Ice | Wind |
|
Flabra | Wind | Earth |
|
Tellus | Earth | Lightning |
|
Sulpor | Lightning | Water |
|
Unda | Water | Fire |
|
Lux | Light | Dark |
|
Tenebrae | Dark | Light |
Harbored runes also determine the effect of Rune Fencer's Ward abilities, Valiance and Pflug, and are expended for effect by the Effusion abilities Lunge and Gambit.
