I'm not sure if this has been brought up anywhere else, or if it is supposed to be like this. But currently if going from skill level 1 in any of the magical elements, you cannot get higher than level 9 meaning you cannot wield the higher level offensive ones, only the defensive.

I travelled to all shops etc and looked through everything all I could find was the following (the same for each element):

lvl1 - basic shield, basic attack
lvl4 - moderate shield (armor)
lvl12 - moderate attack
lvl16 - high attack
lvl20 - very high attack

Personally I think either the basic attack OR the moderate shield should be at skill level 8 meaning you could train your way up these skills. Preferably the shield at 8 and move the basic attack up to 4 so that when starting out people can work their way up to the attack sooner.

Also, while looking at this, I have seen there is no way to advance past 5 in the healing skill with lvl1 being the first skill and lvl8 being the next...

That is all for now! lol
