For Barbarians chasing Overkill, the hunt can feel a bit messy at first, but it gets cleaner once you lock in a route. If you are running Death Blow, this D4 items hunt is worth the time. The weapon is one of those drops that can change how a build plays, so most players stop waiting on random luck and start farming with purpose.

Varshan as the main target

Varshan is the boss most players should focus on. His loot pool can include Overkill, which makes him the best direct shot at the mace. The loop is simple enough: beat Varshan, open the reward chest with a Lair Key, and keep moving. The real bottleneck is keys, so War Plans matter more than people think. If you can keep those runs coming, you will notice progress much faster than with open-world farming.

Why the Heart cache still matters

There is also a nice side route while you are farming him. Each Varshan kill can drop Malignant Hearts, and five of them can be turned into a cache that pulls from his loot table. It is not flashy, but it is solid. You are basically giving yourself another swing at the same reward pool without waiting for a perfect boss drop. Players often ignore this part, then wonder why their farming feels slow. It adds up.

Method What you need Why it helps
Varshan runs Lair Keys Direct access to Overkill's loot pool
Heart cache crafting Five Malignant Hearts Extra roll from the same boss rewards
Item upgrading Base mace and crafting mats Small chance to hit a unique mace

Use your spare resources well

If you have extra Murmuring Obols, gamble for two-handed maces at the Purveyor of Curiosities. That is not the fastest path, and nobody would pretend it is, but it gives you more base items to work with. From there, you can throw spare materials into upgrades and hope for a hit. It is a backup plan, not the plan. Still, it is better than letting those resources sit unused while you are already hunting for the right weapon.

A simple farming loop that works

Run War Plans and stock up on Lair Keys.
Farm Varshan as your main target.
Turn five Malignant Hearts into a cache whenever you can.
Spend spare Obols on two-handed maces.
Use extra crafting mats on upgrades only after the main farm is done.

If you keep that loop going, the hunt starts to feel much less random. You are always pushing toward the same item from a few angles instead of hoping for a miracle drop. That is the kind of farming that saves time, and if you want to speed things up even more, it does not hurt to buy diablo 4 gear when you need to fill the gaps and get back into the run.
