Hey bud, this link will show you on the left of how to level properly (IE: melee sword, you would want Enhanced Effect (EE) and with an armor and charm, full strength on them).
https://ladderslasher.d2jsp.org/The left side in the link shows MANY great attributes like what to stat if you're using a club, axe, sword, dagger, staff, or going caster.
Once you start learning this part of the game, climb a few times solo and ask questions about the game throughout the climb in this topic. People WILL reply if you're doing something right or wrong.
GL!
