I attempted to change “Familiar” to “Ice Blades” on my Enchantress. Although the computer removed Familiar from slot 2, it will nt allow me to add Ice Blades,l leaving slot two blank. I have tried restarting my computer, etc., but the game will not install the new skill. I have tried dragging it over, but it will not enter the blank #2 slot. I have tried the skill assignment tree, and although it will select Ice Blades, it will not install it. Can somebody please explain how to install this skill? Thank you.
