Thought I would test the rates of the artifacts and here's what I got:
[You must be registered and logged in to see this image.]Behemoth Force scroll x 204
Accura Force scroll x 201
Life Force scroll x 144
Extreme Force scroll x 144
Gold Bar x 77
Yellow Candy x 21
Elixir Scroll x 15
Osiris Rank Glove x 5
Osiris Rank Facia x 1
Aquarium pet injection x 1
Chimera Pet injection x 1
Gold coin x 1
It's probably not worth doing this until all the rates are lowered etc.
From the 70 gold bars i got 2 Ancients gem boxes. One had 3 x honour of battlefield silver and the other a kamilla brooch
