Not quite - in my view, Jaune's weapon heirlooms are a sword and a shield, in themselves so generic that they can channel all sorts of variations of aura to varying effects. The benefit of NOT being customized, so to speak.

The 'specialization' of the sword and shield could be to channel and/or augment aura easily, while specific effects will be individual to the wielder of the respective generation.

Or - but that is a wild thought - heirloom weapons being seldom seemingly, may be that one effect is a residual aura/ability effect from previous users...
