The reported Bomb unlock comes from the Produce Industrial Explosives mission chain. Here’s how to craft and equip it, plus the limits of the available Etchspace Salvage boss-route guidance.

The reported unlock for the Bomb utility is the “Produce Industrial Explosives” exploration mission chain—not simply defeating a boss in Etchspace Salvage. After crafting Industrial Explosives, put them in your backpack and select Bomb on the Easy Tool wheel. A precise boss location or turn-by-turn route is not established by the available guide, so use the in-game commission objective rather than relying on a claimed map route.

Requirements reported for Etchspace Salvage

NerdsChalk’s January 28, 2026 walkthrough reports that access to Etchspace Salvage requires Authority Level 25, progress through Chapter 1 – Process 3, and completion of the associated quest. These are secondary-source claims, not confirmed against current official game documentation. Check your quest list and the mode’s in-game requirements, since availability may depend on your current story progress. Source: NerdsChalk

How to unlock and equip Bomb

  1. Wait for the mission chain: The walkthrough says “Produce Industrial Explosives” becomes available after a message from Andre and sufficient main-story progress. Follow the mission as it appears in your game; the guide does not establish an exact point at which Andre’s message arrives.
  2. Use the Packaging production path: The guide describes crafting Industrial Explosives through Packaging and mentions processing Aketine and Amethyst. It does not document a complete recipe or material quantities, so use the requirements shown by your production interface rather than assuming amounts.
  3. Craft the explosives: Complete the production requirements for Industrial Explosives.
  4. Equip the utility for field use: Place Industrial Explosives in your backpack, then select Bomb from the Easy Tool wheel. Crafting the item alone does not complete these reported setup steps.

The walkthrough lists Oroberyl x25, T-Creds, and Intermediate Combat Records as rewards for “Produce Industrial Explosives,” but does not give all amounts. Check the mission’s reward display in your current game before counting on a specific payout. NerdsChalk’s walkthrough

What to do during the Aberrant Exploration boss run

The available route guidance is a broad run sequence, not a verified path to a named boss. No exact boss, map coordinate, location of the Bomb unlock, or sequence of turns is established. Once in Aberrant Exploration, follow the on-screen commission objectives, keep track of Derangement, reach the boss-gated section, defeat the boss, confirm the objective’s progression, and extract. The guide’s description does not prove that defeating this boss unlocks the Bomb utility. NerdsChalk

Endfield Hub’s fan guide describes Derangement as a run constraint affected by combat, looting, and elapsed time, and says explosives can break floating crystal formations. Treat those points as general fan-guide context, not confirmation of a required Bomb objective or an optimal route for this unlock. Endfield Hub: Etchspace Salvage

If Bomb is unlocked but unavailable

  • Confirm Industrial Explosives are actually in your backpack.
  • Open the Easy Tool wheel and check that Bomb is the selected tool.
  • If the mission or utility is still missing, check the current quest display for “Produce Industrial Explosives” and any unmet Etchspace Salvage story or access requirements.

A WoW Quests video result dated January 27, 2026 is also titled as an Industrial Explosives unlock guide, but the video itself was not available for independent review; it does not substantiate a more precise boss route. WoW Quests video listing
