Underdepths Saga: Zaphardt's Defenders

Level 100SignatureHeroic

Walkthrough

Quest Info

Eccles Zaphardt, a gnemlin near the entrance of Maldura, told me that the Alcove of Reason and the Waterworks sections of the city have been locked down due to immolated invasion! In order to explore a possible connection between the threat within the city and the Primordial Malice, I must face them, myself! I should be able to access the Algorithm For Destruction through a door within the Sublevel Access Antechamber.

Steps

Enter Maldura: Algorithm For Destruction (Advanced Solo) .
- Note: Heroic Zone does not use group updates, will have to still use solo zone in order to get everyone the final updates.
- Additional Note: as of 170315, the Heroic version allowed for group updates.
- the pages and springs respawned for all group members to harvest.
- each group member auto-received components from spiders.
- only one group member needed to do crafting for sentries, as all group members received update when sentries were Upgraded.

Complete the subquest, Defensive Measures. Be sure to loot the spider bodies!
Harvest:
- 12 Undertok Sentry Upgrade Plans -- (sheets of paper on the floor in the Waterworks: Treatment and Reclamation area).
  
  undertok upgrade plans
- 8 Undertok Sentry Upgrade Parts -- (looted from the spidermech defenders during Defensive Measures).
  - (NOTE: you must click the crystal at for the spidermech defenders to get feathers. See Subquest Defensive Measures.)
- 1 Cabalbox Access Pin -- (looted from X-O Arachmech during Defensive Measures).
- 8 Coil Conductors -- (these are copper-colored springs found throughout the zone).

- Note: Coil Conductors will become harvestable after using the "Voice Box".
Speak to Eccles Zaphardt by using the Voice Box near the zone-in .

3. Craft 8 Sentry Shock Box XII.
  - There is a workbench in the Alcove of Reason that is found inside the instance. You must use the zone's workbench. Personal workbenches will not display the recipe.
  - Note:You will need 8 Thaumic Coal as fuel for the combine, may bring more if you fail on a combine
Upgrade 8 untertok sentries.
1. Kill the non-aggro, grouped Dark Gears Conscripts and Dark Gears Vassals in the Alcove of Reason.
2. Kill Black Bolt in the Alcove of Reason. See strategy on this.
  - (If you can't attack him, talk to the voice box. You will need to do this before you can upgrade the sentries. It will tell you to find and eliminate a saboteur that is blocking the upgrade process. Now kill Black Bolt.)
3. Use the Sentry Shock Box XII on 8 disabled undertok sentries -- (inconsistent group update; check each character to confirm). If you get garbled speech from the sentries, speak with the Voice Box again.
