The descripton for this ability is inconsistent. Both during level up (upper image) and if you rightclick on the ability in game (lower picture) you see it does pierce damage in one line and crush damage in another.

 

This error is also in german (and most likely in all other languages).

Hey Madscientist,

 

Thanks for bringing this to our attention. I have written up a bug and added it to our database.

 

Thanks a bunch!
