Soul Wardens - why can I only make soul shield 8?

[Bowdon]

I've just started the soul shield wardens guild, so I'm at level 1.

 

I noticed that I could make soul shields. But for some reason I can only make soul shield 8.

 

If I increase rank in the guild will it let me make shields for the other positions?

No you will not be able to make other parts. This soul shield is not supposed to be used. It is meant to be infused into another soulshield, since it has extremely high values on one single stat.

I gathered that it would need to be fused to another soul shield. So we can only fuse this one part? I wanted crit x 8 lol

Ok, I've realised I can't fuse it with the diva soul shield. Can I only fuse it with a higher shield level?
