Using windows 7, v0.1.11
And given that the error message SEEMS to mention the cockatrice’s artifact, here it is:
The asuras have artifacts too, but they have nothing in their sockets.
Also, while the cockatrice isn’t fused, the asuras are fused. Here are the abilities they received from fusion, in the same order that they appear in the bottom of the first screenshot: Wrecking Ball, Urdox Harbinger, Sidewinder, Wretchedness, and Frenzy.
As for my spec and perks: Tribalist, Battalion MAX, Feign Death MAX, Forest Pack MAX, and nothing else.
Thanks for all the information! Should be able to have this fixed for the next patch.
