same for me dropped first time on my 1st and 3rd char but on my 2nd char no chance to get it... seriously bugged.Would be nice to be able to purchase all crafting specs and not be specific drops from enemies. I got the Psalm gun my first play through. Decided to do a better 2nd play thru and way past the quest to get this spec. And it did not drop the 2nd time, but did the 1st. This is the only spec I need to fill out my weapons stash.
