Some Endgame Viable Skills for Every Class. There are quite a few weak and mediocre skills in Diablo 2 so choose very carefully or you may have to re-create your character if you've already used your first Den of Evil Respec: Only focus on maxing out 1-2 main attack skills and their synergies or else your skills will become too weak later on.
You can max out each skill with 20 points, although bonuses to skills from gear pushes this beyond 20. After that the only way to respec is to farm the Act bosses in Hell difficulty to create respec tokens.
You Only Get 1 Skill Respec Per Difficulty for completing the Den of Evil quest. Also a refresher if you're coming back after a long break.
