training a weapon is a waste of your LP… until the very end that is..
First max out str, then and only then consider putting points…
The vast majority of the game, swords are the best weapon you can have… but the ultimate weapon is a hammer that is considered an Axe… and gives +6, so a skill of 4 in axes is max you should ever need.
Oh, it is a one handed axe that allows a shield in other hand and swings like a one handed sword...
