I did some of the storyline apparently out of order, explains why I was coming across areas that I could not access or cross. I'm still really enjoying it, although my combat is obviously ****-poor as it took me about 50 goes to chop off the arms of the one boss, didn't help that it took me ages to figure out that once he goes full on beserk he keeps knocking your sword out of your hand. The only good thing about it is that when you die you retain the XP from the previous failed attempts....all the attempts at beating that one boss moved me from LV14 to L16 !.
Many of the caves etc I enter have baddies in them that just seem far too strong for me, and I guess coming back later doesn't help much because they will get stronger as I do.
And its just in the last couple of days, after a good 25+ hrs play that I am getting the significance of the earth/fire/water image that appears below your inventory page, it is telling you which elemental stone you need fitted to your weapons to do most damage to enemies that are doing elemental attacks. Water stone to fight fire is obvious, but the rest not so much. For example I assumed somebody doing water damage was best attack with fire damage. I hadn't noticed the ">" signs between them.
