EMP Locations

To craft EMPs, you first need the recipe, which you receive after defeating Voltatia the Power Master. This also grants the recipe for Power Cores.

Build a Fabricator in your castle. You likely already have one from defeating Ziva the Engineer, a Level 60 Act III boss.

Farm Tech Scrap from enemies and crates in the Gloomrot area.

To craft one EMP, you need nine Iron Ingots and three Power Charges. Each craft yields five EMPs.

Iron Ingots can be obtained by smelting Iron Ore.

Power Charges require six Radium Alloys and three Charged Batteries.

To get Charged Batteries, head to the Trancendum Power Plant in Gloomrot North and farm Depleted Batteries from enemies and crates.

Take the Depleted Batteries to a Lightning Harvester, found in the Stormdrain Hills area southwest of Gloomrot North, and deposit them to charge. You must charge them in batches of 10.

Return to your Fabricator with Charged Batteries and Radium Alloy to craft Power Cores. Each craft produces two Power Cores.

You need three Power Cores for one EMP craft, so ensure you farm enough Radium Alloy and Charged Batteries to perform two Power Core crafts (to get six Power Cores), which will allow you to craft five EMPs.
