Guild Wars 2

Ok so I’ve been searching for a website that has good information for people doing recipe research in the mystic forge and everyone has pointed me to the wiki. i know all about the wiki. i have added to the wiki many times myself.

however it does not say a single thing about what recipes use the obsidian shards other than for mystic clovers. unverified recipes such as

shard + ecto + coins + scroll

i was dropping random tiems today and found this one, does anyone know what it makes? and has anyone found any other recipes that use the shards?

There are not so many weapons left, maybe a couple , i can be wrong too. So, nothing new left to discover using so much expensive mats, as much we know

Thats pretty much same as 1x and 10x clover recipes, instead having a scroll in it.
But I have some shards and karma left myself and wonder if they can be used for smth.
