I had saved every single cosmic since day one.
I made the time to clean inventory.
Most of them were T1's and some were powered up to 10 or 20.
I was surprised how little value they were. In the beginning they were so hard to get.... and now they sell for next to nothing.
I get so many w/ a special stat, yet 90% of the toons have no fury..... so kind of a waste.
I know some have attacks based off special stat, but still not as important as a good Hp & attk/mag or both.
Getting cosmic souls is more about the gold these days.
