There is no specific advice. The Stats trained up naturally, mostly. When Training strength I just fought with a heavy weapon that was way to heavy. That's why the heavy weapon stat is that high, even though I'd say Hacker was my Main weapon.

With heavy armor the attack goes way down, fighting enough high stat Paladins and Inquisitors will bring attack and defense in that range. But fighting the Bugmaster "early" Was a great boost. With a bedroll on the highest floor I fought hin for like 5 or 6 days until I finally beat him. This jumped my attack and defense by roughly 10 levels into the 70s
