The bug has already been reported the 22th december.
Please DEVs, for the love of the Emperor, do something for this!
I have spent lot of time to get good Rashad combat axe to discover that they are bugged.
Antax axe have similar moves… maybe you could exploit that to fix this axe. I perfectly know that the two axes have different modifiers, but it should not affect the move… at least I hope cause this weapon, as it is actually, is totally useless.
