Hi i'm looking for help in understanding crafting mechanics.
My crafting levels are arcane22/divine6/elemental5

I was able to craft a shard of VICIOUS (or vicious shard)
I was able to craft a shard of +3 enhancement
I have a blank greataxe

I thought i had all the pre-requisites but i'm unable to bind anything (binding vicious alone wont work, binding +3 alone with the greataxe wont work either).

Where am i misunderstanding the process?

Thanks
