I read the instructions on the comments page, but I was specifically referring to the UI prompt that popped up, I was not able to get past it. No worries though, great game!
for that you need to spec exactly the skills required to get the tutorial popup to go away.
the skills required are the Sword, Fire skill in the Staff tree, and then the Enchant skill which is on the upper right of the Staff tree, this turns your Fire into an Enchant fire skill
