Runes are non-consumables, they are simply JAs so far as I gather.

SE- Runes will be activated through the use of abilities. As mentioned at VanaFest, there are both offensive and defensive types of runes. Offensive runes will mainly be used against enemies dealing elemental damage and such, while defensive runes will mainly be used on yourself and party members to reduce elemental damage.

Rune fencers will also be able to utilize enhancing magic, so like paladins they will also utilize and consume MP.
Could be wrong, just how I interpreted it at least.
