Runesmith/Rune Mage (RSM)/(RMG) Concept

I thought of something that should be done and that is aetherial gear crafting: taking HQ Gear and giving it aetherial properties or something. than i thought of how gear loses durability and not every one has high level crafters to repair their own gear in battle. then i came up with this

Battle job with crafting enhancement abilities

Battle: one handed runic hammer and shield

Role: Support

Discipline: War

Gear: Same Gear that LNC/DRG uses like chainmail

Abilities:
Lightning Smite. Summon a bolt of lightning that arcs from the hammer & smites a single enemy.

Fire Circle. Smash hammer into the ground and explode enemies in a circle around it. RUNIC CIRCLE: Enemies in the circle suffer burning over time & are susceptible to ice.

Some abilities to slow or prevent durability loss

Can repair other peoples gear in the field like in dungeons

Could nullify spirit bonds

Feedback would be great as this is all i got so far.
