Located Deep within the Abyssal Wastelands, the player can rarely stumble across this structure, or use Powerstone Trackers to find the stronghold in a consistent matter. Each Stronghold holds a Dreadlands Infused Powerstone, along with an Abyssal Zombie Spawner as the end reward. In order to harvest a Dreadlands Infused Powerstone, a Refined Coralium Pickaxe is required.
Bring lots of food, a completely zoomed out map, and at least a stack of Powerstone Trackers and Torches to mark your way. It is risky to bring a Horse into the Abyssal Wastelands, as the randomly spawned Shoggoths will home in on the Horse and consume it for Biomass Collection. Mobs will impede your path to the stronghold, so it's best to carry tons of weapons to drive back the oncoming horde. Ensure to have a Refined Coralium Pickaxe on hand to harvest the Infused Powerstone.
