I put one point into frozen armor which should allow me to get shiver armor but it won’t let me take it it’s still red.
I just went to an online skill calculator and realize what the problem is and it’s the overlay you forgot to put the branch between ice blast and shiver armor. So it doesn’t show that you need those two scales to get shiver armor.
More specifically upon further testing that is on the controller layout not the mouse and keyboard layout.
I copy/pasted it a bug report that was made during the beta, on April 12th. The bug is still there, even though it was marked as closed back then.
