Need some help crafting Leviathan

I have the materials, but have never found the blueprint on any character.

Can somebody craft it for me? I will tip.

Thanks

I am new - to get this crafting done do you meet in a cooperative game, craft, top and both exit? Is that how all this trading and crafting happens?

Go to the trade forums and ask around. And yes, you get into a coop game, trade the mats, the guy makes it for you and trades it back.

What is a appropriate tip for crafting one of these?
