Bone Ring +1 to Minimum Endurance Charges

Hi,

I'm following a POB for zoomancer, I'm supposed to get

"+1 to Minimum Endurance Charges" on my bone ring.

I can't find much information on how to get that, is it available through a crafting bench recipe or somewhere else?

Thanks!

Crafting bench but you have to get craft from syndicate ring unveils. Its random to get in from any veiled ring.

Or amulet as well.
