You'll get the chance to hire your first mercenary

There's plenty of loot when playing D2R Items however most of it isn't necessary to acquire. While you are able to sell items to town in the future, returning can quickly become tedious and can cost you a little amount in the form of the Scroll of Town Portal. Therefore, your time is better spent in acquiring more useful items.

Items that are particular to specific classes such as sacred globes, wands as well as scepters and barbarian helmets etc. are a excellent option, as are rings/amulets and items that provide the opportunity to demonstrate one of the skills of the class. Try to find them instead of bolts or other low-value objects that are a waste of space. You can maximize your earnings while reducing the amount of trips to town you need to take.

Get ready to grind

Diablo 2 doesn't have an endgame that you'd expect from a modern game, and in the end, you'll likely spend much of your time playing boss battles, where you'll constantly fight an opponent to gain better items. However, even before you reach that point, you may discover that you're not as strong, so it's important to grind XP (and possibly earn useful items) by repeating specific sections in the game. Tristram The Countess, Tristram the catacombs of Act 1, Act 2's tombs and Act 3's council etc. are great grounds for earning more XP frequently than usual. Be prepared to work your way through these multiple times.

As previously mentioned, the Necromancer's ability in summoning allies vital to keep some stress off your shoulders. Fortunately, everyone can enlist help even without diving into multiplayer. While you're progressing through the initial Act 1 story, you'll get the chance to hire your first mercenary through Kashya (one of the NPCs in Act 1's Act 1 town, the Rogue Encampment). There are several types of mercenaries you'll be able to buy diablo II resurrected items employ as you progress through the game, beginning with the bow-wielding Rogues of Act 1.
