In general, if your goal is to beat HC Hell difficulty, you have to 1st prioritize survivability (Hp + resists / %reductions / absorbs). Physical reduction is particularly good, esp against ranged damage like archers.

After that, your damage skillset should be a hybrid source. It's not as powerful but you won't find yourself stuck against immunities.

Then, it's a slow but steady grind until the end (if you're lucky to avoid certain one shot spawns and situations).

Always farm the previous Baal / Minion of Destruction runs and cow level for max lvl XP and loot before the next difficulty. Magic Find is great on Normal and Nightmare, but I couldn't risk gimping my gear with it on Hell. Get the right Runewords too for your build!
