Like KinnisonArc sais, these terrible looking weapons are likely relic "Zenith" weapons.
To upgrade these to the next stage "Atma" they need to farm 12 Atma which are a possible drop from FATEs, but they can only drop if you have a Relic "Zenith" weapon equiped.

Furthermore, each Atma drops in a specific zone and some of them are in low level zones.

So no, they aren't there to help the newby.
