Where to Find Etna's Lost Dagger in Diablo 4

While it can drop as random loot anywhere in Sanctuary, relying purely on luck will take a long time. Use these specific endgame farming strategies to get the dagger efficiently:

1. The Target Farm: Harbinger of Hatred

The most reliable way to find the weapon is by defeating the Harbinger of Hatred endgame boss. This boss holds the highest drop priority for the dagger on official community databases like the Maxroll Boss Loot Table.

2. The Kurast Undercity

Running the Kurast Undercity is another highly successful method. Players in the D4Rogue Reddit Community report finding the dagger quickly by burning "Mythic" Tributes before starting their Undercity runs. This guarantees high-tier Unique weapon rewards at the end layout.

3. The Horadric Cube Crafting Method

If boss fights are not dropping the weapon, use crafting mechanics to force it. Collect standard white (Common) quality Daggers and use the "Upgrade to Unique" recipe.

Pro Crafting Tip: If you have rare or magic daggers with good item power, use the "Remove Affix" function first to strip them down into clean common weapons before upgrading them.

1. Twisting Blades Poison Assassin

This build combines high mobility with heavy damage over time (DoT). By pairing the Bladedancer aspect with Poison Imbuement, your blades melt entire rooms of enemies. Adding Etna's Lost Dagger gives the build a massive endgame damage spike.

It allows your filler basic attacks to spread deadly poison explosions rapidly.

2. Multi-Element Basic Skill Build

This playstyle targets fast-attacking basic moves like Heartseeker. Once the dagger's unique power triggers, your standard basic attacks turn into heavy-hitting elemental strikes.

This gives you infinite, high-damage attacks without draining your Energy resource pool.

Community Strategy Tip

To make triggering the dagger incredibly simple without changing your favorite skills, follow the meta strategy used on the Blizzard Class Forums.

Roll a "Lucky Hit: Chance to Deal Elemental Damage" affix onto your Unique Charm, Rings, or Gloves. If your main build uses Poison Imbuement, a lucky hit that deals Cold or Shadow damage instantly triggers the dagger’s maximum damage buff automatically.
