Frost from frag weapon doesn't work.

[vastilos]

I would like to know why frost doesn't work when I double click on it like it says I should. I unequip and re-equip my frag weapon and nothing. I 2x, 3x, 4x, up to 100x click on frost and it still won't activate.

You need to drag it onto your hotkeybarslots and single-time click it there like you'd click any other skill.

When you forge you frag your automatically get given a new frost skill so if it is in your hotkey A take it off and put it back on and try again.
