My endurance is 30, and vitality at 20. I kept my dex and strength at 18. That seems to be the maxing point if you would max one and keep the other at 18. I hear great things about both... However, I simply cannot decide. At first I was all about dex, until I faced some people with Havel's armor/Black Knight axe that just wrecked me.
Which is another thing. I seem to be missing out on all the good strength weapons. Didnt get the Asylum hammer, didnt get the demon axe (A scaling weapon), and I fought the three black knights I know, didnt get a black knight weapon. Now unless I can fight an unlimited supply of black knights late game to try to get the Black Knight axe, I see a problem.
Then there are some that say mixing a little pyromancy works wonders.
